Connections to bulk bias tees and various mis-matched loads degrade th
e usable frequency response of high-speed photodetectors. Monolithic i
ntegration of passive components to enhance the realizable performance
of high-bandwidth, long-wavelength photodiodes is demonstrated. Circu
its having bias tees and matched resistors integrated with 7-mu m x 7-
mu m photodiodes show unsable electrical bandwidths exceeding 100 GHz.
