Booster Optical Amplifiers (BOAs) are single-pass, traveling-wave amplifiers that perform well with both monochromatic and multi-wavelength signals. Since BOAs only amplify one state of polarization, they are best suited for applications where the input polarization of the light is known. For applications where the input polarization is unknown or fluctuates, a Semiconductor Optical Amplifier (SOA) is required. However, the gain, noise, bandwidth, and saturation power specifications of a BOA are superior to that of an SOA because of the design features that make the SOA polarization insensitive.

The BOA consists of a highly-efficient InP/InGaAsP Multiple Quantum Well (MQW) layer structure. As seen in the schematic to the right, the input and output of the amplifier is coupled to the reliable ridge waveguide on the optical amplifier chip. Losses typically range from 1.5 to 2.5 dB at both the fiber-to-chip and chip-to-fiber couplings. These coupling losses affect the total gain, noise figure (NF), and saturation power (Psat). While the gain produced by the amplifier exceeds that of the losses, these losses remain an important factor in determining the device's performance. For instance, a 1 dB drop in input coupling efficiency increases the noise figure by 1 dB. Alternatively, a 1 dB drop in output coupling decreases the saturation power by 1 dB.

The device is contained in a standard 14-pin butterfly package with either SMF or PMF pigtails that are terminated with FC/APC connectors. The connector key is aligned to the slow axis on all PMF pigtailed models. Optional polarization-maintaining isolators at the input, output, or both input/output are also available (specifications may vary with different configurations). Please contact Tech Support to order such a device.

Our BOA1132P optical amplifier is also available in the S9FC1132P benchtop optical amplifier.

Driver Option
The CLD1015 butterfly LD/TEC controller is one possible controller for these amplifiers. This LD/TEC controller and mount combination offers full control via a touch screen. When operating the BOAs on this page with the CLD1015, the orientation for type 1 pin configurations should be used.

Center Wavelength Note
The center wavelength (CWL) of the amplified spontaneous emission (ASE) spectrum in broadband semiconductor devices such as optical amplifiers may show variation between lots. Please refer to the Specs tab for the CWL tolerances of each particular model. For applications in which a specific ASE center wavelength is a critical concern, please contact tech support for information on the CWL of currently available lots.

Comparison of a SOA to a standard Fabry-Perot Laser Diode

Semiconductor Optical Amplifiers (SOAs and BOAs) are similar in design to Fabry-Perot Laser Diodes. The difference being that Fabry-Perot laser diodes have reflective coatings on both end faces of the semiconductor chip. The optical feedback from the reflective end faces establishes a cavity in which lasing can occur. SOAs and BOAs have an anti-reflection (AR) coating on both end faces of the semiconductor chip. The AR coatings limit the optical feedback into the chip so that lasing does not occur.

As is typical for all amplifiers, SOA/BOAs operate in two regimes: a linear, flat, constant gain regime and a non-linear, saturated output regime. When used to amplify a modulated signal, the linear regime is typically used to eliminate pattern-dependent distortion, multi-channel cross-talk and transient response issues common to EDFAs. The non-linear regime is used to take advantage of the highly non-linear attributes of the semiconductor gain medium (cross-gain modulation, cross phase modulation) to perform wavelength conversion, optical 3R regeneration, header recognition, and other high-speed optical signal processing functions.

For a CW input signal, the amount of power that can be produced by the amplifier is determined by the saturation output power (Psat) parameter. Psat is defined as the output power at which the small-signal gain has been compressed by 3 dB. The maximum amount of CW power that can be extracted is approximately 3 dB higher than the saturation power.

Hello, thank you for contacting Thorlabs. What specific BOA are you asking for the PDG of? Unfortunately, we currently do not offer polarization insensitive SOAs in the O-band.

Dear Sir, Could you please let me know the spontaneous emission power of the BOA1017S? We are planing to build an system by using this amplifier. Thank you Chih

Hello Chih, thank you for contacting Thorlabs. I have reached out to you directly with a plot of the total ASE power vs drive current.

Yes, the BOA can be driven using the CLD1015. This information is given on the Overview tab of this page.

I would like to know how much spontaneous emission comes out when, for example, 4mW is input, and 40mW (or max output) is produced. Do you have any output spectra representative of these devices for a seed in the O-band. Thx. Jeff White
besembeson  (posted 2016-05-04 02:53:59.0)
Response from Bweh at Thorlabs USA: For a 700mA drive current, we have a plot for the amplified spontaneous emission spectrum (ASE) under the "Graphs" tab. The gain variation with output power was measured at 1312nm, which is in the O-band.
udaytronic  (posted 2016-04-26 07:28:56.21)
Hi, I was looking for maximum input optical power for those amplifiers in the specs. But I don't see them. Could you please let me know where to find or may be you can update them. Thanking you
besembeson  (posted 2016-04-26 09:46:56.0)
Response from Bweh at Thorlabs USA: We do specify the saturation power, and the maximum output power that can be extracted from any of these devices is 3dB higher than the saturation power. So you should keep your input power to a maximum level with the amplification factor (which is wavelength and drive current dependent) and saturation power in mind.
