Abstract:

The goal of this program was to develop key concepts for optical symbolic computing. During the course of the program, both a top-down and bottom-up approach was taken to develop an architecture for symbolic computing. The approach was intended to result in an architecture suitable for the design goals while being implementable with practical components. Key results of the program include the following Design of a unique symbolic processing architecture, Identification of lack of suitable addressable optical memory as a major impediment in the implementation of existing paradigms, Demonstration of a unique, critically needed polarization based modulator with 17 dB extinction ratio, and demonstration of the worlds highest extinction ratio 23 dB of AlGaAsGaAs modulator at 1 GHz, and Demonstration of high density modulator arrays with the worlds smallest pitch 20 um and less than 20 dB crosstalk. rh
