Conventional single-photon detectors such as avalanche photodiodes (APDs) have the main advantage of an internal gain mechanism when a high reverse bias voltage is applied. However, the drawbacks are large dark counts, the necessity of high-voltage power supply, operation speed limited by the long recovery time, etc. Since these issues are overcome by detecting photo-generated carriers one by one without multiplication. Due to the remarkable progress in silicon integrated circuit (IC) technology, a short- and narrow- channel silicon-on-insulator (SOI) metal-oxide-semiconductor field-effect transistor (MOSFET) could detect single electrons at room temperature. In this work, the signal processing method for the SOI MOSFET single-photon detector is studied. Hardware implementation of single-photon counting in real-time based on field-programmable gate array (FPGA) is considered. It is further advantageous to realize the output signal from the detector in real-time rather than to route the signal in software to get the output.
