Abstract

In this letter, an InGaAs-on-Si single photon avalanche diode (SPAD) for telecommunication wavelengths is presented. This SPAD demonstrates high-single-photon quantum efficiency and low-dark-count probability under gated mode operation. We attributed the good performance of this device to the high absorption coefficient of InGaAs and low noise avalanche multiplication of Si.
