Abstract

The study of an avalanche photodiode with an undepleted p-type InGaAs absorption region and a thin InAlAs multiplication layer was performed. The purpose for utilizing an undepleted absorption layer was to reduce the dark current. The demonstration of a drak current below 1 nA at a gain of 10 and a gain-bandwidth product of 160 GHz was done.
