Radiation-Resistant Optical Fiber Amplifiers for Satellite Communications

Optical fiber amplifiers are key building blocks in laser communication terminals and telecom photonic payloads. In this paper we present 1.55 ?m booster amplifiers and pre-amplifiers suitable for satellite to ground, inter-satellite links and flexible photonic payloads. We validate the designs in the relevant space environment by characterizing the performance against ionizing radiation and report on functional performance of the amplifiers over temperature, in thermal vacuum and after vibration and mechanical shock.
