A rigorous theoretical analysis for an In0.53Ga0.47As/InP single photon avalanche photodiode under Geiger mode operation

A single-element passive quenching with active reset (PQAR) circuit is proposed. Its operation mechanism is studied in theory to show that this single element, based on thyristor, can provide similar function of quenching and reset for the free-running Geiger-mode operation of single photon avalanche diodes (SPADs) as the conventional PQAR circuits, but with significant simplicity. Requirement for the thyristor is identified, and an InP sample was designed, fabricated and characterized. Future work for further demonstration is also discussed.

Geiger Mode

In this paper, we experimentally characterize the Inga As/Imp avalanche photodiode (APD), which is working in Geiger mode, so as to choose the single photon detector for quantum communication. Due to the fact that bias of APD tends to be flat after avalanche, we first adopt the methodology of passive quenching to determine dark breakdown voltage. Experiment results indicate that temperature reduction will widen the optimal operating region and increase the optimal multiplication; therefore APD will be more sensitive. Epitaxial APD is the best choice for single-photon detection among the APDs we have tested for its low noise level and high signal-to-noise ratio (SNR). Finally, we design a mixed passive-active quenching integrated circuit with gate control, which is quick with the quenching time of about 25ns and has controllable dead time with minimum of about 60ns.

Scintillating Fiber

ABSTRACTThe tracking of high energy, secondary products in the Superconducting Super Collider (SSC) presents challenging sensitivity and timing requirements for the scintillating fiber converters and the optical radiation detectors planned for use as signal readouts. Silicon Avalanche Photodiodes (APD) are very promising detectors which may ultimately meet these requirements.We have designed and manufactured 1 mm2 APDs, to be operated in Geiger mode as single photon detectors for the SSC. The progress on decreasing the APD response time by platinum doping, device thinning and external avalanche quenching is reported.
