Abstract
We have measured the dark current (Id) and noise equivalent power (NEP) of four large-area (~0.8 cm2) avalanche photodiodes (APD) to determine their sensitivity limit for detecting weak optical communication signals. We found that from room temperature down to about -10°C the Id decreased by one-half for every 8-deg drop in temperature and the NEP decreased by one-half for every 16-deg drop in temperature. Below this temperature, the NEP leveled off at somewhat less than 5 pW in a 100-kHz bandwidth. We describe the measurement technique, present an analysis of the data, and discuss the statistical properties of these APDs according to the model developed by McIntyre et al.
