Abstract
LIDAR is used for understanding the operating environment for naval activity, where profiling LIDAR systems have been developed for detection of mines. One critical component of the system is a photodetector, and the proposed research will develop a high-performance detector for 400500 nm light. Photomultiplier tubes have the bandwidth and signal amplification needed but are bulky and have poor quantum efficiency. Compact solid-state sensors made some wide-band gap semiconductors address these issues but tend to be noisy. The Phase-1 effort will identify the performance-limiting noise source, often associated with material quality, focusing on wide-band-gap Ga-based materials, such as GaP and AlGaAs, to reduce the room temperature dark current. The Phase-2 effort will develop a plan to mitigate the performance limitations and fabricate a high-efficiency, high-bandwidth photodetector prototype for Naval LIDAR.
