Arrays of III-V semiconductor Geiger-mode avalanche photodiodes

Abstract

In this paper, InGaAsP/InP APDs is designed for detection of near infrared (1-1.5 /spl mu/m wavelength) light and GaN APDs designed for detection of ultraviolet (<365 nm wavelength) light. This paper will also describe ladar measurements which use arrays of G-M APDs matched with timing circuits to produce 3D images with near-infrared photons.
