Abstract :
Operation in the 800-nm window has become of increased interest for LAN and subscriber loop applications. High component count in such systems makes microwave monolithic integrated circuits (MMICs) very attractive in seeking even lower cost solutions. In this paper, two metal-semiconductor-metal (MSM) photodetectors fabricated using no modifications to standard MMIC foundry processes are examined. The devices, each with seven interdigitated electrode fingers, were fabricated on GaAs-GaAlAs pHEMT and GaAs MESFET (M-MSM) processes
