Abstract:In this paper, we report the temperature stability and robust performance of our avalanche photodiode (APD), as well as the wide dynamic range and high gain linear mode detection ability of our receiver module prototype. The APDs have a low dark current and low-temperature coefficient of operating voltages from 19.2 to 22.7 mV/℃ with a gain from 10 to 200. The high sensitivity APD-transimpedance amplifier (TIA) receiver module (TIA gain 22 kV/A) demonstrates measured NEP value of 29 fW/Hz 0.5 when APD operates… Show more
