Our multimode fluoride fiber patch cables are designed for low-loss transmission in the mid-IR spectral range. Manufactured using Thorlabs' fluoride optical fiber, these patch cables have a wide transmission range over which attenuation is relatively flat and are AR-coated for 4.0 - 4.6 µm. This coating helps reduce reflections at the connector that could affect sources sensitive to feedback such as our Quantum Cascade Lasers (QCLs) and Turnkey QCL Systems. The AR-coated cables were tested with a laser source operating near 2.5 W and found to operate well to at least 40 kW/cm2, which is sufficient for use with the QCL sources recommended here. For more information on using these fibers with QCL systems, please see the MIR Applications tab.

Fluoride fiber offers flatter attenuation in the mid-IR than silica fiber; a comparison of the attenuation of uncoated fluoride fibers and Low-OH Silica fibers is presented in the graph to the right. The extended transmission range of InF3 up to 4.6 µm makes it ideal for AR coating in the 4.0 - 4.6 µm range. Thorlabs also offers uncoated ZBLAN zirconium fluoride (ZrF4) patch cables, which have a transmission range of 285 nm - 4.5 µm. AR-coated silica patch cables are offered in the range of 250 - 370 nm, 400 - 700 nm, or 650 - 1100 nm.

Custom Patch Cables

Fluoride fiber patch cables offer mechanical flexibility similar to standard silica patch cables and good environmental stability. Visible light (such as that generated by fiber-coupled lasers) can be propagated along the fiber as an alignment aid since fluoride glass transmits down into the UV. The numerical aperture (NA) of the patch cables remains constant over their specified attenuation ranges (see the Graphs tab).

The ends of each cable are terminated using metal ferrule connectors that are compatible with SMA905-terminated components. Each cable includes two stainless steel protective caps that shield the ferrule ends from dust and other hazards. Replacement CAPM (rubber) and CAPSM (metal) caps for SMA905-terminated cables are available separately.

Stocked AR-coated InF3 patch cables are available in 1 m lengths. Custom patch cable lengths are available by contacting Tech Support.

Usage Recommendations
Fluoride glass is softer than standard silica glass, which means extra care should be taken when cleaning these patch cables. Dry wipes should not be used on these cables as they can damage the AR coating. Please see the Handling tab for fluoride-fiber-specific usage tips. Compared to unterminated fiber, the maximum power that these cables can withstand is limited by the connectors. Depending on the application, we recommend not exceeding a maximum CW power of several Watts when using these cables.

We are continuously refining our processes for these new materials to reduce the variations between runs. If you are concerned that the fiber you receive will not satisfy your needs, please contact Tech Support for details on what is currently available.

The CO2 4.3 µm band has a stronger signal using the AR-coated InF3 fiber than the uncoated InF3 fiber. The shaded region represents the 4.0 - 4.6 µm AR coating range of the fiber.

These AR-coated InF3 patch cables can help improve spectroscopy, environmental monitoring, and chemical sensing applications. Major absorption bands for CO, CO2, and N2O all occur between 4.0 µm and 4.6 µm. The AR coating on these cables helps to propagate the signature generated by these molecules with reduced loss to reflections, leading to improved signal. This increase in signal can be seen in example data from the CO2 4.3 µm absorption band shown in the graph to the right. The experimental setup that collected this data used an FTIR spectrometer with an InSb detector. White light from the FTIR is coupled into the fiber using an Off-Axis Parabolic (OAP) mirror. A second OAP mirror then couples light from the fiber into the InSb detector. The FTIR has open air spaces between the fiber output and the detector into which CO2 gas was introduced through respiration. Scans were made in the absence of respiration to establish a baseline and then the performance of the AR-coated InF3 patch cable was compared to the performance of the uncoated InF3 patch cable (Item # MF11L1). Although this experiment was elementary, it indicates that the AR coating on the InF3 patch cables can aide spectroscopy and other chemical sensing applications in the 4.0 - 4.6 µm range.

As mentioned in the Overview tab, our 4.0 - 4.6 µm AR-coated InF3 patch cables significantly reduce harmful reflections to sources sensitive to feedback, such as QCLs. We highly recommend using these cables when working with MIR Fabry-Perot lasers such as Item #s MLQF4000 (center wavelength of 4.00 µm) or MLQF4550 (center wavelength of 4.55 µm). To couple a light source into the Ø100 InF3 core, a spot size of approximately 70 µm is needed. These Turnkey QCL lasers have a beam diameter of approximately 1.75 mm, giving an ideal focal length of f = 21.4 mm for the IR lens used to couple light into these Ø100 core patch cables. To couple light from MLQF4000 or MLQF4550 to the fiber, we recommend a translation stage (Item # MBT616D) with an SMA adapter (Item # HFB001B), a fixed angle bracket (Item # AMA009), an appropriate lens mount (HCS0xx series), and the IR lens (Si Plano-Convex, BaF2 Plano-Convex, or ZnSe Plano-Convex) best suited to your needs. To ensure minimal back reflections, optics can be mounted at a slight angle.

With the addition of a 500 nm wide bandpass filter centered around 4250 nm (Item # FB4250-500), these AR-coated InF3 patch cables are also well matched to white light sources such as Item # SLS202L, a stabilized fiber-coupled IR light source providing a blackbody radiation spectrum spanning from the visible into the MIR. Some application examples are shown in the photos below.

This tab describes the key similarities and differences between standard silica patch cables and fluoride patch cables in day-to-day usage.

Physical Handling

Bending
For protection, the fluoride patch cables are jacketed with stiffer materials than those used with typical patch cables. Our Ø100 µm core InF3 cables have plastic (PVDF polymer) jackets. The fiber will remain intact as long as the jacket is not forced to bend. The plastic jacket will become discolored if the bending limit is exceeded. Please refer to the spec table below for the specified bend radii.

Storage
Since fluoride glass is softer than standard silica glass, it scratches more easily. Hence, it is especially important to use the included protective caps to protect the end faces when the patch cable is not being used. Replacement CAPM (rubber) and CAPSM (metal) caps for SMA905-terminated cables can be purchased separately.

Cleaning
Use the FS201 Fiber Inspection Scope to examine the tip of the fiber. If particulates are present, first try removing them using a gentle flow of compressed air. If compressed air is insufficient, then our FCC-7020 Fiber Connector Cleaner or MC-5 Lens Tissues dampened with a solvent like methanol can be used to clean the tip.

Please note that Kimwipes®† are extremely likely to scratch the fiber tip and should not be used. Dry tissues should be dampened using a solvent such as methanol to protect the AR coating and the fiber.

Polishin
It is not recommended to use our polishing supplies with fluoride fiber patch cables. If the tip of the fiber becomes scratched, repolishing may be appropriate; consider contacting Tech Support to make use of this service.

Environmental Considerations

Normal lab temperatures and humidities will not affect the integrity of the fiber. Prolonged, direct contact with liquid water or water vapor should be avoided.

End-of-Life Disposal

Thorlabs will accept and safely dispose of fluoride patch cables that you wish to discard. Please contact Tech Support before returning the cable. If you wish to dispose of the cable locally, please follow all applicable local laws and regulations, noting that the fluoride glass is composed primarily of barium fluoride with zirconium fluoride or indium fluoride.

Total Internal Reflection in an Optical Fiber

Guiding Light in an Optical Fiber

Optical fibers are part of a broader class of optical components known as waveguides that utilize total internal reflection (TIR) in order to confine and guide light within a solid or liquid structure. Optical fibers, in particular, are used in numerous applications; common examples include telecommunications, spectroscopy, illumination, and sensors.

One of the more common glass (silica) optical fibers uses a structure known as a step-index fiber, which is shown in the image to the right. Step-index fibers have an inner core made from a material with a refractive index that is higher than the surrounding cladding layer. Within the fiber, a critical angle of incidence exists such that light will reflect off the core/cladding interface rather than refract into the surrounding medium. To fulfill the conditions for TIR in the fiber, the angle of incidence of light launched into the fiber must be less than a certain angle, which is defined as the acceptance angle, θacc. Snell's law can be used to calculate this angle:

where ncore is the refractive index of the fiber core, nclad is the refractive index of the fiber cladding, n is the refractive index of the outside medium, θcrit is the critical angle, and θacc is the acceptance half-angle of the fiber. The numerical aperture (NA) is a dimensionless quantity used by fiber manufacturers to specify the acceptance angle of an optical fiber and is defined as:

In step-index fibers with a large core (multimode), the NA can be calculated directly using this equation. The NA can also be determined experimentally by tracing the far-field beam profile and measuring the angle between the center of the beam and the point at which the beam intensity is 5% of the maximum; however, calculating the NA directly provides the most accurate value.

 

Number of Modes in an Optical Fiber

Each potential path that light propagates through in an optical fiber is known as a guided mode of the fiber. Depending on the physical dimensions of the core/cladding regions, refractive index, and wavelength, anything from one to thousands of modes can be supported within a single optical fiber. The two most commonly manufactured variants are single mode fiber (which supports a single guided mode) and multimode fiber (which supports a large number of guided modes). In a multimode fiber, lower-order modes tend to confine light spatially in the core of the fiber; higher-order modes, on the other hand, tend to confine light spatially near the core/cladding interface.

Using a few simple calculations, it is possible to estimate the number of modes (single mode or multimode) supported by an optical fiber. The normalized optical frequency, also known as the V-number, is a dimensionless quantity that is proportional to the free space optical frequency but is normalized to guiding properties of an optical fiber. The V-number is defined as:

where V is the normalized frequency (V-number), a is the fiber core radius, and λ is the free space wavelength. Multimode fibers have very large V-numbers; for example, a Ø50 µm core, 0.39 NA multimode fiber at a wavelength of 1.5 µm has a V-number of 40.8.

For multimode fiber, which has a large V-number, the number of modes supported is approximated using the following relationship.

In the example above of the Ø50 µm core, 0.39 NA multimode fiber, it supports approximately 832 different guided modes that can all travel simultaneously through the fiber.

Single mode fibers are defined with a V-number cut-off of V < 2.405, which represents the point at which light is coupled only into the fiber's fundamental mode. To meet this condition, a single mode fiber has a much smaller core size and NA compared to a multimode fiber at the same wavelength. One example of this, SMF-28 Ultra single mode fiber, has a nominal NA of 0.14 and an Ø8.2 µm core at 1550 nm, which results in a V-number of 2.404.

Sources of Attenuation

Loss within an optical fiber, also referred to as attenuation, is characterized and quantified in order to predict the total transmitted power lost within a fiber optic setup. The sources of these losses are typically wavelength dependent and range from the material used in the fiber itself to bending of the fiber. Common sources of attenuation are detailed below:

Absorption
Because light in a standard optical fiber is guided via a solid material, there are losses due to absorption as light propagates through the fiber. Standard fibers are manufactured using fused silica and are optimized for transmission from 1300 nm to 1550 nm. At longer wavelengths (>2000 nm), multi-phonon interactions in fused silica cause significant absorption. Fluoride glasses such as ZrF4 and InF3 are used in manufacturing Mid-IR optical fibers primarily because they exhibit lower loss at these wavelengths. ZrF4 and InF3 fibers have a multi-phonon edge of ~3.6 µm and ~4.6 µm, respectively.

Contaminants in the fiber also contribute to the absorption loss. One example of an undesired impurity is water molecules that are trapped in the glass of the optical fiber, which will absorb light around 1300 nm and 2.94 µm. Since telecom signals and some lasers operate in that same region, any water molecules present in the fiber will attenuate the signal significantly.

The concentration of ions in the fiber glass is often controlled by manufacturers to tune the transmission/attenuation properties of a fiber. For example, hydroxyl ions (OH-) are naturally present in silica and absorb light in the NIR-IR spectrum. Therefore, fibers with low-OH content are preferred for transmission at telecom wavelengths. On the other hand, fibers with high-OH content typically exhibit increased transmission at UV wavelengths and thus may be preferred by users interested in applications such as fluorescence or UV-VIS spectroscopy. 

Scattering
For the majority of fiber optics applications, light scattering is a source of loss that occurs when light encounters a change in the refractive index of the medium. These changes can be extrinsic, caused by impurities, particulates, or bubbles; or intrinsic, caused by fluctuations in the glass density, composition, or phase state. Scattering is inversely related to the wavelength of light, so scattering loss becomes significant at shorter wavelengths such as the UV or blue regions of the spectrum. Using proper fiber cleaning, handling, and storage procedures may minimize the presence of impurities on tips of fibers that cause large scattering losses.

Bending Loss
Losses that occur due to changes in the external and internal geometry of an optical fiber are known as bending loss. These are usually separated into two categories: macrobending loss and microbending loss.

Macrobend loss is typically associated with the physical bending of an optical fiber; for example, rolling it in a tight coil. As shown in the image to the right, guided light is spatially distributed within the core and cladding regions of the fiber. When a fiber is bent at a radius, light near the outer radius of the bend cannot maintain the same spatial mode profile without exceeding the speed of light. Instead, the energy is lost to the surroundings as radiation. For a large bend radius, the losses associated with bending are small; however, at bend radii smaller than the recommended bend radius of a fiber, bend losses become very significant. For short periods of time, optical fibers can be operated at a small bend radius; however, for long-term storage, the bend radius should be larger than the recommended value. Use proper storage conditions (temperature and bend radius) to reduce the likelihood of permanently damaging the fiber; the FSR1 Fiber Storage Reel is designed to minimize high bend loss.

Microbend loss arises from changes in the internal geometry of the fiber, particularly the core and cladding layers. These random variations (i.e., bumps) in the fiber structure disturb the conditions needed for total internal reflection, causing propagating light to couple into a non-propagating mode that leaks from the fiber (see the image to the right for details). Unlike macrobend loss, which is controlled by the bend radius, microbend loss occurs due to permanent defects in the fiber that are created during fiber manufacturing.

Cladding Modes
While most light in a multimode fiber is guided via TIR within the core of the fiber, higher-order modes that guide light within both the core and cladding layer, because of TIR at the cladding and coating/buffer interface, can also exist. This results in what is known as a cladding mode. An example of this can be seen in the beam profile measurement to the right, which shows cladding modes with a higher intensity in the cladding than in the core of the fiber. These modes can be non-propagating (i.e., they do not fulfill the conditions for TIR) or they can propagate over a significant length of fiber. Because cladding modes are typically higher-order, they are a source of loss in the presence of fiber bending and microbending defects. Cladding modes are also lost when connecting two fibers via connectors as they cannot be easily coupled between optical fibers.

Cladding modes may be undesired for some applications (e.g., launching into free space) because of their effect on the beam spatial profile. Over long fiber lengths, these modes will naturally attenuate. For short fiber lengths (<10 m), one method for removing cladding modes from a fiber is to use a mandrel wrap at a radius that removes cladding modes while keeping the desired propagating modes.

 

Launch Conditions

Underfilled Launch Condition
For a large multimode fiber which accepts light over a wide NA, the condition of the light (e.g., source type, beam diameter, NA) coupled into the fiber can have a significant effect on performance. An underfilled launch condition occurs when the beam diameter and NA of light at the coupling interface are smaller than the core diameter and NA of the fiber. A common example of this is launching a laser source into a large multimode fiber. As seen in the diagram and beam profile measurement below, underfilled launches tend to concentrate light spatially in the center of the fiber, filling lower-order modes preferentially over higher-order modes. As a result, they are less sensitive to macrobend losses and do not have cladding modes. The measured insertion loss for an underfilled launch tends to be lower than typical, with a higher power density in the core of the fiber. 

Diagram illustrating an underfilled launch condition (left) and a beam profile measurement using a FT200EMT multimode fiber (right).

Overfilled Launch Condition
Overfilled launches are defined by situations where the beam diameter and NA at the coupling interface are larger than the core diameter and NA of the fiber. One method to achieve this is by launching light from an LED source into a small multimode fiber. An overfilled launch completely exposes the fiber core and some of the cladding to light, enabling the filling of lower- and higher-order modes equally (as seen in the images below) and increasing the likelihood of coupling into cladding modes of the fiber. This increased percentage of higher-order modes means that overfilled fibers are more sensitive to bending loss. The measured insertion loss for an overfilled launch tends to be higher than typical, but results in an overall higher output power compared to an underfilled fiber launch. 

Diagram illustrating an overfilled launch condition (left) and a beam profile measurement using a FT200EMT multimode fiber (right).

There are advantages and disadvantages to underfilled or overfilled launch conditions, depending on the needs of the intended application. For measuring the baseline performance of a multimode fiber, Thorlabs recommends using a launch condition where the beam diameter is 70-80% of the fiber core diameter. Over short distances, an overfilled fiber has more output power; however, over long distances (>10 - 20 m) the higher-order modes that more susceptible to attenuation will disappear. 

Thorlabs Lab Facts: Modifying Beam Profiles with Multimode Fibers

We present laboratory measurements demonstrating how the output beam profile from multimode fiber can be affected by the beam entry angle. In some applications, an alternative beam distribution such as a top hat or donut is desired instead of the inherent Gaussian distribution provided by typical optics. Here we investigated the effect of changing the input angle of a focused laser beam into a multimode fiber patch cable. Focusing the light normal to the fiber face produced a near-Gaussian output beam profile (Figure 1) and increasing the angle resulted in top hat- (Figure 2) and donut-shaped (Figure 3) beam profiles. These results demonstrate how multimode fibers can be used to change the shape of a beam profile.

For our experiment, we used an M38L01 Ø200 µm, 0.39 NA, Step-Index Fiber Patch Cable (Bare Fiber Item # FT200EMT) as the test fiber into which we launched the focused laser beam. The input light was set incident at 0°, 11°, and 15° to the input face of the multimode fiber to create the initial, top hat, and donut profiles, respectively. Each time the angle was changed, the alignment of the input fiber was optimized while the output power was monitored with a power meter to ensure maximum coupling was achieved. Images were then acquired with a 9 second exposure and the shape of the beam profile was evaluated. Note that during the exposure, a 1500 grit diffuser was manually rotated between the coupling optics (before the fiber under test) to reduce the spatial coherence and create a clean output beam profile.

Assuming a ray tracing model, there are two general types of rays that propagate along a multimode fiber: (a) meridional rays, which pass through the central axis of the fiber after each reflection, and (b) skew rays, which never pass through the central axis of the fiber. The figures below illustrate the three basic ray propagation scenarios observed during the experiment. Figures 4 and 6 depict meridional and skew ray propagation through multimode fiber, respectively, and the associated theoretical beam distribution at the fiber output. As illustrated in Figure 6, skew rays propagate in a helical path along the fiber that is tangent to the inner caustic of the path with radius r. Figure 5 depicts the beam propagation and beam distribution from a combination of meridional and skew rays. By changing the input angle of the light launched into a multimode fiber, we were able to modify the proportion of light rays propagating as meridional rays vs. skew rays, and consequently, modify the output from a near-Gaussian distribution (primarily meridional rays, see Figure 1) to a top hat (mixture of meridional and skew rays, see Figure 2) to a donut (primarily skew rays, see Figure 3). The beam profiles shown in Figures 4 through 6 were obtained at a distance of 5 mm from the fiber end face. These results demonstrate the ability to use a standard multimode fiber patch cable as a relatively inexpensive method to modify an input Gaussian profile into a top hat and donut profile with minimal loss.
