Abstract
Free space optical communication (FSOC) systems offer rapid data transfer rates, allowing practical wireless relay of complex data sets. To further promote the use of this technology for medium-range optical communication links operating with eye-safe ultra-violet (UV) sources, compact and robust receiver modules with high responsivity that operate in a range of environmental conditions are required. To meet this challenge, scientists at Radiation Monitoring Devices, Inc. (RMD) will further advance our state-of-the-art silicon avalanche photodiode (APD) technology. Our goal is to realize a manufacturing process that reliably produces APDs with quantum efficiencies of greater than 80% in the 350 to 380 nm wavelength range, operation at temperature ranging from -40 to 70 degrees C, bandwidths of at least 100 MHz and less than 90 V operation bias. This effort will build upon our established planar processing methods, without sacrificing its advantages; namely, large area APD detectors with high quantum efficiencies and signal gains greater than 1000. When coupled to high-speed amplification electronics, a receiver module will be realized that meets required performance specifications as defined by the US Army.
