Abstract :
A measurement system for determining the gain distributions of avalanche photodiodes (APDs) in a low gain range is presented. The system is based on an ultralow-noise charge-sensitive amplifier and detects the output carriers from an APD. The noise of the charge-sensitive amplifier is as low as 4.2 electrons at a sampling rate of 200 Hz. The gain distribution of a commercial Si APD with low average gains is presented, demonstrating the McIntyre theory in the low gain range.
