The Role of Photodetectors in Optical Signal Processing.

Abstract

Optical signal processing applications place demands on photodetector arrays beyond those encountered in image sensing applications. We review the basic requirements and show that increased dynamic range and non-linear decision operations that lead to reduced output data rates are the key improvements needed for both one and two dimensional arrays. Arrays of high-speed photodetector elements, with integrated post-detection circuitry, are also needed. We suggest some possible methods for achieving these goals; our main objective is to stimulate the photodetector community to design and fabricate more useful devices. Keywords include: Optical processing, and Detectors.
