Manuscript Abstract:

Near-infrared linear mode Al0.85Ga0.15As0.56Sb0.44 avalanche photodiodes (APDs) exhibit excellent temperature stability, potentially simplifying Geiger mode operation. We have carried out the first experimental evaluation of In0.53Ga0.47As/Al0.85Ga0.15As0.56Sb0.44 APDs in Geiger mode. Characterization on multiple devices included temperature-dependent dark current, avalanche multiplication, dark count rate (DCR), afterpulsing, and single photon detection efficiency (SPDE). The temperature coefficient of breakdown voltage extracted from avalanche multiplication data was 13.5 mV.K−1, much lower than InGaAs/InP Geiger mode APDs, reducing changes in operation voltage and offering possible protection from high optical power thermal attack in communication systems. At 200 K, SPDE were 5%–16% with DCR of 1–20 Mc·s−1, comparable to InAlAs and early InP-based Single Photon APDs. The afterpulsing at 200 K was negligible for hold-off time >50 µs (reducing to 5 µs at 250 K). These are similar to the performance of InGaAs/InAlAs and some InGaAs/InP Geiger mode APDs.
