High Current Photodetector

For many communication, applications the demand for more bandwidth is a never ending problem. Military system applications often can exceed commercial demands by an order of magnitude or more as SIGINT and IMINT data collection and transmission are keys to our National Security. Optical delivery of RF signals is an increasingly important topic for applications including RF antenna remoting, signal routing, CATV, wireless repeaters and tunnels, in-building coverage, and surveillance and reconnaissance. Communication systems using optical signals are a common approach for both military and commercial applications and advancements made for one application form the foundation for advancements in another application. In this phase II program, Archcom will develop fiber pigtailed photodiode modules with responsivities of 0.7A/W, bandwidths of 20GHz, photocurrent handling capabilities of 50mA, and output IP3s of 30dBm to target these applications. Archcom will also investigate advanced WGPD structures to increase the photocurrent handling capability to 100mA and the output IP3 to 60dBm.
