Paper Abstract

We present a variety of uncooled, packaged InGaAs photodiode and photoreceiver modules that have been successfully qualified, or are in the process of being qualified, for several space applications. These devices include multi-gigahertz 1060 nm to 1650 nm wavelength lattice-matched InGaAs photodetectors, lattice-mismatched InGaAs photodetectors for extended wavelength up to 2200 nm, and large-area ultra-low noise quad photoreceivers for gravitational wave detection. We describe the qualification process which involves a combination of MIL-STD tests, such as mechanical shock and vibration, proton and gamma radiation laboratory experiments, and successful space flight on-board the International Space Station through MISSE missions.
