Abstract

The single-photon detection efficiency of various commercial InGaAs/InP avalanche photodiodes (APDs) operated in the Geiger mode has been reported previously. These studies showed substantial photon detection efficiency variation between individual devices, but did not indicate what device parameters might be responsible for this variation. We present data on the external single-photon detection efficiency of APDs operated as near-infrared single photon counters, and show how detection efficiency is related to both device design and operating conditions. We have fabricated APDs with near-infrared single-photon detection efficiency exceeding 50% at 10% excess bias, demonstrating that InGaAs/InP APDs of the proper design are well suited to many practical applications of photon counting in the 1.0 to 1.7 micron wavelength band.
