Compact And Robust Pattern Recognizer Using A Micro-Laser Array

Eung Gi Paek, A. Von Lehmen, J. R. Wullert II, and R. Martin

Although the classical coherent optical processor has been widely used in many different fields of analog optical computing, pattern recognition, neural networks, and optical interconnects, its bulky volume and critical alignment requirements make its integration difficult. Furthermore, for an optical computing/processing system to be practical, it is important to be integrable with semiconductor technology to facilitate the interfacing with other devices. The recent invention of surface-emitting laser diode arrays (SELDAs) opened many possibilities in the field of optical computing. In particular, the compact two-dimensional nature of SELDA makes possible compact optical signal processing systems.
