The single-photon avalanche-photodiode (SPAD) discussed in this work uses a mainstream deep-submicron CMOS technology in order to achieve ultrahigh-speed operation and high pixel fill-factor, with ...

Abstract: Back-illuminated modified uni-traveling-carrier photodiodes (MUTC-PDs) are optimized to achieve high power and wide bandwidth. The fabricated 6-μm-diameter PD demonstrates a 3-dB bandwidth ...
