Features
Thorlabs has integrated our fiber-coupled optical amplifiers into easy-to-use benchtop units. To use, simply connect fiber patch cables with FC/APC connectors to the input and output connectors and set the drive current and temperature with the dial on the front panel. The drive current can be modulated at up to 250 kHz using an input signal from 0 - 5 V (corresponding to zero transmission and maximum gain, respectively) via a BNC connector located on the rear panel of the unit. An internal microcontroller ensures that the amplifier is not overdriven from the modulation voltage. The unit's LCD displays the drive current and measured temperature of the amplifier, as well as the center wavelength of the unit and the amplifier type (SOA or BOA). The USB interface allows these amplifiers to be controlled remotely via a PC (see the manual for a list of commands for running the unit from a command line interface). BOA vs. SOA For butterfly packaged BOAs and SOAs, please see our 1050 nm, O-Band, E-Band, C-Band, and L-Band offerings.

General SpecificationsThe following specifications apply to all of the BOAs and SOAs in the tables above.
SOA Performance PlotsBOA Performance PlotsS9FC1137P: 1050 nm Center Wavelength![]() Semiconductor and Booster 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 (see the diagrams to the right). The optical feedback from the 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 (see the plot below). 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.
