Deep Ultraviolet Avalanche Photodetectors (DUVAP)
Abstract
(U)This program demonstrated avalanche photodiodes (APDs) operating in the Geiger mode, i.e. capable of counting single photons with high gain. The APDs operate in the ultraviolet, in the band centered at 280 nanometers (nm), and are designed to be insensitive to the solar flux. The two classes of materials pursued were Silicon Carbide (SiC) and Aluminum Gallium Nitride (AlGaN). The U.S. military has a need for compact, reliable, and cost-effective Geiger-mode photodetectors. Avalanche photodetectors offer high gain, low dark count, high reliability and robustness, and small form factor needed in future military applications. Technology will transition via industry.
