Features

  • Wavelength Division Multiplexers (WDMs) for Infrared Signals (≥980 nm)
  • Combine or Split Two Wavelengths (See Table to the Right for Wavelength Combinations)
  • Ideal for Fiber Lasers, Fiber Amplifiers, or Other Telecom Applications
  • Combine 1050 nm, 1300 nm, or 2000 nm Signals with a Pump Source or Visible Alignment Beam
  • Available with Bare Fiber Ends, FC/PC, or FC/APC Connectors (Other Connectors Upon Request)

Wavelength Division Multiplexers (WDMs) are used to combine or split two different single mode signals with low insertion loss. Thorlabs' WDMs featured on this page are manufactured using Fused Biconic Taper (FBT) technology and are designed for common NIR and telecom wavelengths (see the table to the right for options). They are an ideal solution for combining pump and signal wavelengths in fiber lasers and amplifiers or for combining telecom signals.

Because most WDMs are bidirectional, they can also be used to split two wavelengths entering the common port into two separate output ports. Thorlabs also offers 1050 nm / 635 nm, 1300 nm / 650 nm, and 2000 nm / 600 - 800 nm WDMs that allow the IR signal to be combined with a pump source or visible alignment beam. However, since visible light is below the cut-off wavelength of the fiber in these WDMs, they are not bidirectional, and should not be used to split light. Thorlabs also offers single mode WDMs designed for 473 nm - 785 nm and polarization-maintaining WDMs.

Our WDMs are offered from stock with 2.0 mm narrow key FC/PC or FC/APC connectors or with unterminated leads. Other fiber types and select wavelength combinations are available upon request. Please contact Tech Support with inquiries. Thorlabs also offers a wide range of single mode fiber connectors and a fiber termination kit.

Wavelength Division Multiplexer Design

Thorlabs' Wavelength Division Multiplexers (WDMs) are designed to combine or split light at two different wavelengths. Thorlabs offers a variety of multiplexers with wavelength combinations spanning the visible, near-IR, and IR regions of the spectrum. Our visible wavelength division multiplexers are also known as "wavelength combiners" as they are commonly used in microscopy applications to generate multi-color composite images. 

The animation to the right illustrates the basic operating principles of a 1x2 WDM. When combining light, the wavelength-specific ports will transmit light within a specified bandwidth region and combine them into a multi-wavelength signal output at the common port, with minimal loss in signal. 

Except where indicated, our WDMs are bidirectional; they can also split a two-wavelength signal that is inserted into the common port into the component wavelengths. For optimal combining/splitting performance, the input signal(s) should contain only the wavelengths specified for the WDM. An insertion loss graph can help determine the transmission and coupling performance within and outside the specified bandwidth. For our WDMs that have red, engraved housings, this data is included with the item-specific datasheet that ships with each coupler.

The shaded regions in the plot indicate the bandwidth where each port meets the specified performance.

Insertion Loss and Isolation
WDM performance is typically quantified using insertion loss. As seen in the definition below, insertion loss (measured in dB) is the ratio of the input power to the output power from each leg of the WDM. For optical systems, the definition of insertion loss is given as:

Insertion Loss

where Pin and Pout are the input and output powers (in mW). 

Each port of the coupler is designed to have low insertion loss (i.e., high transmission) at the desired wavelength while suppressing the signal at the specified wavelength of the other port, which minimizes cross talk between the ports. Therefore, isolation is specified as the insertion loss of these undesired wavelengths. High dB values of isolation are ideal for signal separation applications using a WDM. For example, in the graph shown to the right, the long wavelength port (shown using a red dashed line) has a low insertion loss around 640 nm (indicated by the red shaded region), but exhibits high isolation (>25 dB) in the region specified for the short wavelength port (indicated by the light blue shaded region).

Wavelength Division Multiplexer Manufacturing Process

This section details the steps used in manufacturing and verifying the performance of our wavelength division multiplexers.

In the diagram, the fibers are color-coded; blue for the short wavelength port and red for the long wavelength port.  

Step 1

At the first stage, two fibers are fused on a manufacturing station so that the two fiber cores are in close proximity. This allows light to propagate between the two fiber cores over the fused region in a process known as evanescent coupling. The fusing process is stopped once the desired insertion loss and isolation specifications are achieved.

The output from the short wavelength port is monitored during the fusing process using a broadband source on one side and an optical spectrum analyzer (OSA) on the other. The insertion loss as a function of wavelength is calculated from the spectrum obtained from the OSA.

In the diagram, the fibers are color-coded; blue for the short wavelength port and red for the long wavelength port.

Step 2

To verify the WDM performance, the output is measured in the long wavelength port using a broadband source and OSA. By combining the plots obtained in steps 1 and 2, the insertion loss and isolation in each channel can be calculated. 

Laser-Induced Damage in Silica Optical Fibers

The following tutorial details damage mechanisms relevant to unterminated (bare) fiber, terminated optical fiber, and other fiber components from laser light sources. These mechanisms include damage that occurs at the air / glass interface (when free-space coupling or when using connectors) and in the optical fiber itself. A fiber component, such as a bare fiber, patch cable, or fused coupler, may have multiple potential avenues for damage (e.g., connectors, fiber end faces, and the device itself). The maximum power that a fiber can handle will always be limited by the lowest limit of any of these damage mechanisms.

While the damage threshold can be estimated using scaling relations and general rules, absolute damage thresholds in optical fibers are very application dependent and user specific. Users can use this guide to estimate a safe power level that minimizes the risk of damage. Following all appropriate preparation and handling guidelines, users should be able to operate a fiber component up to the specified maximum power level; if no maximum is specified for a component, users should abide by the "practical safe level" described below for safe operation of the component. Factors that can reduce power handling and cause damage to a fiber component include, but are not limited to, misalignment during fiber coupling, contamination of the fiber end face, or imperfections in the fiber itself. For further discussion about an optical fiber’s power handling abilities for a specific application, please contact Thorlabs’ Tech Support.

Damaged Fiber End

Damage at the Air / Glass Interface

There are several potential damage mechanisms that can occur at the air / glass interface. Light is incident on this interface when free-space coupling or when two fibers are mated using optical connectors. High-intensity light can damage the end face leading to reduced power handling and permanent damage to the fiber. For fibers terminated with optical connectors where the connectors are fixed to the fiber ends using epoxy, the heat generated by high-intensity light can burn the epoxy and leave residues on the fiber facet directly in the beam path.

  • All values are specified for unterminated (bare) silica fiber and apply for free space coupling into a clean fiber end face.
  • This is an estimated maximum power density that can be incident on a fiber end face without risking damage. Verification of the performance and reliability of fiber components in the system before operating at high power must be done by the user, as it is highly system dependent.
  • This is the estimated safe optical power density that can be incident on a fiber end face without damaging the fiber under most operating conditions.

Damage Mechanisms on the Bare Fiber End Face

Damage mechanisms on a fiber end face can be modeled similarly to bulk optics, and industry-standard damage thresholds for UV Fused Silica substrates can be applied to silica-based fiber. However, unlike bulk optics, the relevant surface areas and beam diameters involved at the air / glass interface of an optical fiber are very small, particularly for coupling into single mode (SM) fiber. therefore, for a given power density, the power incident on the fiber needs to be lower for a smaller beam diameter.

The table to the right lists two thresholds for optical power densities: a theoretical damage threshold and a "practical safe level". In general, the theoretical damage threshold represents the estimated maximum power density that can be incident on the fiber end face without risking damage with very good fiber end face and coupling conditions. The "practical safe level" power density represents minimal risk of fiber damage. Operating a fiber or component beyond the practical safe level is possible, but users must follow the appropriate handling instructions and verify performance at low powers prior to use.

Calculating the Effective Area for Single Mode and Multimode Fibers
The effective area for single mode (SM) fiber is defined by the mode field diameter (MFD), which is the cross-sectional area through which light propagates in the fiber; this area includes the fiber core and also a portion of the cladding. To achieve good efficiency when coupling into a single mode fiber, the diameter of the input beam must match the MFD of the fiber.

As an example, SM400 single mode fiber has a mode field diameter (MFD) of ~Ø3 µm operating at 400 nm, while the MFD for SMF-28 Ultra single mode fiber operating at 1550 nm is Ø10.5 µm. The effective area for these fibers can be calculated as follows:

SM400 Fiber: Area = Pi x (MFD/2)2 = Pi x (1.5 µm)2 = 7.07 µm= 7.07 x 10-8 cm2

 SMF-28 Ultra Fiber: Area = Pi x (MFD/2)2 = Pi x (5.25 µm)2 = 86.6 µm= 8.66 x 10-7 cm2

To estimate the power level that a fiber facet can handle, the power density is multiplied by the effective area. Please note that this calculation assumes a uniform intensity profile, but most laser beams exhibit a Gaussian-like shape within single mode fiber, resulting in a higher power density at the center of the beam compared to the edges. Therefore, these calculations will slightly overestimate the power corresponding to the damage threshold or the practical safe level. Using the estimated power densities assuming a CW light source, we can determine the corresponding power levels as:

SM400 Fiber: 7.07 x 10-8 cm2 x 1 MW/cm2 = 7.1 x 10-8 MW = 71 mW (Theoretical Damage Threshold)
     7.07 x 10-8 cm2 x 250 kW/cm2 = 1.8 x 10-5 kW = 18 mW (Practical Safe Level)

SMF-28 Ultra Fiber: 8.66 x 10-7 cm2 x 1 MW/cm2 = 8.7 x 10-7 MW = 870 mW (Theoretical Damage Threshold)
           8.66 x 10-7 cm2 x 250 kW/cm2 = 2.1 x 10-4 kW = 210 mW (Practical Safe Level)

The effective area of a multimode (MM) fiber is defined by the core diameter, which is typically far larger than the MFD of an SM fiber. For optimal coupling, Thorlabs recommends focusing a beam to a spot roughly 70 - 80% of the core diameter. The larger effective area of MM fibers lowers the power density on the fiber end face, allowing higher optical powers (typically on the order of kilowatts) to be coupled into multimode fiber without damage.

Damage Mechanisms Related to Ferrule / Connector Termination


Click to Enlarge
Plot showing approximate input power that can be incident on a single mode silica optical fiber with a termination. Each line shows the estimated power level due to a specific damage mechanism. The maximum power handling is limited by the lowest power level from all relevant damage mechanisms (indicated by a solid line).

Fibers terminated with optical connectors have additional power handling considerations. Fiber is typically terminated using epoxy to bond the fiber to a ceramic or steel ferrule. When light is coupled into the fiber through a connector, light that does not enter the core and propagate down the fiber is scattered into the outer layers of the fiber, into the ferrule, and the epoxy used to hold the fiber in the ferrule. If the light is intense enough, it can burn the epoxy, causing it to vaporize and deposit a residue on the face of the connector. This results in localized absorption sites on the fiber end face that reduce coupling efficiency and increase scattering, causing further damage.

For several reasons, epoxy-related damage is dependent on the wavelength. In general, light scatters more strongly at short wavelengths than at longer wavelengths. Misalignment when coupling is also more likely due to the small MFD of short-wavelength SM fiber that also produces more scattered light.

To minimize the risk of burning the epoxy, fiber connectors can be constructed to have an epoxy-free air gap between the optical fiber and ferrule near the fiber end face. Our high-power multimode fiber patch cables use connectors with this design feature.

Determining Power Handling with Multiple Damage Mechanisms

When fiber cables or components have multiple avenues for damage (e.g., fiber patch cables), the maximum power handling is always limited by the lowest damage threshold that is relevant to the fiber component. In general, this represents the highest input power that can be incident on the patch cable end face and not the coupled output power.

As an illustrative example, the graph to the right shows an estimate of the power handling limitations of a single mode fiber patch cable due to damage to the fiber end face and damage via an optical connector. The total input power handling of a terminated fiber at a given wavelength is limited by the lower of the two limitations at any given wavelength (indicated by the solid lines). A single mode fiber operating at around 488 nm is primarily limited by damage to the fiber end face (blue solid line), but fibers operating at 1550 nm are limited by damage to the optical connector (red solid line).

In the case of a multimode fiber, the effective mode area is defined by the core diameter, which is larger than the effective mode area for SM fiber. This results in a lower power density on the fiber end face and allows higher optical powers (on the order of kilowatts) to be coupled into the fiber without damage (not shown in graph). However, the damage limit of the ferrule / connector termination remains unchanged and as a result, the maximum power handling for a multimode fiber is limited by the ferrule and connector termination. 

Please note that these are rough estimates of power levels where damage is very unlikely with proper handling and alignment procedures. It is worth noting that optical fibers are frequently used at power levels above those described here. However, these applications typically require expert users and testing at lower powers first to minimize risk of damage. Even still, optical fiber components should be considered a consumable lab supply if used at high power levels.

Intrinsic Damage Threshold

In addition to damage mechanisms at the air / glass interface, optical fibers also display power handling limitations due to damage mechanisms within the optical fiber itself. These limitations will affect all fiber components as they are intrinsic to the fiber itself. Two categories of damage within the fiber are damage from bend losses and damage from photodarkening. 

Bend Losses
Bend losses occur when a fiber is bent to a point where light traveling in the core is incident on the core/cladding interface at an angle higher than the critical angle, making total internal reflection impossible. Under these circumstances, light escapes the fiber, often in a localized area. The light escaping the fiber typically has a high power density, which burns the fiber coating as well as any surrounding furcation tubing.

A special category of optical fiber, called double-clad fiber, can reduce the risk of bend-loss damage by allowing the fiber’s cladding (2nd layer) to also function as a waveguide in addition to the core. By making the critical angle of the cladding/coating interface higher than the critical angle of the core/clad interface, light that escapes the core is loosely confined within the cladding. It will then leak out over a distance of centimeters or meters instead of at one localized spot within the fiber, minimizing the risk of damage. Thorlabs manufactures and sells 0.22 NA double-clad multimode fiber, which boasts very high, megawatt range power handling.

Photodarkening
A second damage mechanism, called photodarkening or solarization, can occur in fibers used with ultraviolet or short-wavelength visible light, particularly those with germanium-doped cores. Fibers used at these wavelengths will experience increased attenuation over time. The mechanism that causes photodarkening is largely unknown, but several fiber designs have been developed to mitigate it. For example, fibers with a very low hydroxyl ion (OH) content have been found to resist photodarkening and using other dopants, such as fluorine, can also reduce photodarkening.

Even with the above strategies in place, all fibers eventually experience photodarkening when used with UV or short-wavelength light, and thus, fibers used at these wavelengths should be considered consumables.

Preparation and Handling of Optical Fibers

General Cleaning and Operation Guidelines
These general cleaning and operation guidelines are recommended for all fiber optic products. Users should still follow specific guidelines for an individual product as outlined in the support documentation or manual. Damage threshold calculations only apply when all appropriate cleaning and handling procedures are followed.

  1. All light sources should be turned off prior to installing or integrating optical fibers (terminated or bare). This ensures that focused beams of light are not incident on fragile parts of the connector or fiber, which can possibly cause damage.

  2. The power-handling capability of an optical fiber is directly linked to the quality of the fiber/connector end face. Always inspect the fiber end prior to connecting the fiber to an optical system. The fiber end face should be clean and clear of dirt and other contaminants that can cause scattering of coupled light. Bare fiber should be cleaved prior to use and users should inspect the fiber end to ensure a good quality cleave is achieved.

  3. If an optical fiber is to be spliced into the optical system, users should first verify that the splice is of good quality at a low optical power prior to high-power use. Poor splice quality may increase light scattering at the splice interface, which can be a source of fiber damage.

  4. Users should use low power when aligning the system and optimizing coupling; this minimizes exposure of other parts of the fiber (other than the core) to light. Damage from scattered light can occur if a high power beam is focused on the cladding, coating, or connector.

Tips for Using Fiber at Higher Optical Power
Optical fibers and fiber components should generally be operated within safe power level limits, but under ideal conditions (very good optical alignment and very clean optical end faces), the power handling of a fiber component may be increased. Users must verify the performance and stability of a fiber component within their system prior to increasing input or output power and follow all necessary safety and operation instructions. The tips below are useful suggestions when considering increasing optical power in an optical fiber or component.

  1. Splicing a fiber component into a system using a fiber splicer can increase power handling as it minimizes possibility of air/fiber interface damage. Users should follow all appropriate guidelines to prepare and make a high-quality fiber splice. Poor splices can lead to scattering or regions of highly localized heat at the splice interface that can damage the fiber.

  2. After connecting the fiber or component, the system should be tested and aligned using a light source at low power. The system power can be ramped up slowly to the desired output power while periodically verifying all components are properly aligned and that coupling efficiency is not changing with respect to optical launch power.

  3. Bend losses that result from sharply bending a fiber can cause light to leak from the fiber in the stressed area. When operating at high power, the localized heating that can occur when a large amount of light escapes a small localized area (the stressed region) can damage the fiber. Avoid disturbing or accidently bending fibers during operation to minimize bend losses.

  4. Users should always choose the appropriate optical fiber for a given application. For example, large-mode-area fibers are a good alternative to standard single mode fibers in high-power applications as they provide good beam quality with a larger MFD, decreasing the power density on the air/fiber interface.

  5. Step-index silica single mode fibers are normally not used for ultraviolet light or high-peak-power pulsed applications due to the high spatial power densities associated with these applications.

Response from Javier at Thorlabs to Juergen: Thank you for your feedback. Although we do not have data regarding the coupling efficiency that you can expect from using a 635 or 660 nm laser at one of the inputs and cannot guarantee the performance, we believe that you should be able to couple either one of these wavelengths with enough efficiency for alignment of your setup. I will contact you directly with information regarding an FC/APC version of these WDMs.

Wavelength Division Multiplexers: 1050 nm / 635 nm

RGB Combiner
Click for Details

The housings of these WDMs are engraved with the Item # and port wavelengths. The common port is located on the single fiber side and has a white jacket.
  • Combine a 1050 nm Signal with a 635 nm Alignment Beam 
  • ±50 nm Bandwidth at 1550 nm
  • Includes a Product-Specific Data Sheet (Click Here for a Sample)
  • HI1060 or HI1060 FLEX Fiber Options
  • Available with Unterminated Fiber Leads or with 2.0 mm Narrow Key FC/PC or FC/APC Connectors

The W635S415 WDMs are designed for combining an alignment beam at around 635 nm with a 1050 nm signal. They can handle a maximum power of 300 mW with connectors or bare fiber and a maximum power of 500 mW when spliced (see the Damage Threshold tab for more details). Because of the large ±50 nm bandwidth at 1050 nm, this multiplexer is ideal for applications in life science imaging. Unlike other WDMs on this page, these WDMs are unidirectional because light at 635 nm will be multimode. They should not be used to split light. They are available with no connectors or with 2.0 mm narrow key FC/PC or FC/APC connectors.

These WDMs are available with HI1060 or HI1060 FLEX fiber. HI1060 fiber offers a Ø5.3 µm core size and a 0.14 NA, while HI1060 FLEX fiber offers a Ø3.4 µm core size, a 0.22 NA, and reduced bending loss relative to HI1060.
