Paper Abstract

Optical detectors and processing electronics are key elements of electrooptical systems. It is nearly always the goal of the designer to develop a combination that works with less light than previously achieved. The results of a development effort that focuses on a heated avalanche protodiode and hybrid transimpedance preamp are discussed. Evaluations are performed to identify the operating parameters that maximize the threshold detection of pulses. With the package case held at 20 C, the best sensitivity of less than 2.0 nW was found for a responsivity of 1.2 to 2.2 MV/W depending on the temperature. Sensitivity remained approximately the same from a photodiode temperature of 20 to 50 C.
