Abstract

The advantage of optical signal processing and computing is mainly due to its two-dimensional complex computing ability with the fastest speed. Of computation algorithms, quite a few are iterative or recursive, such as vector or matrix multiplication over a given matrix for many times, and the computation of derivatives of much high order, etc. These algorithms are also suitable for optical computing . To perform iterative algorithms, the output from a computation step reenters the system as the input for the next step, therefore a feedback loop is needed. Many optical signal processing systems have spatial light modulators that are electrically addressed, and the photon-to-electron and electron-to-photon conversions reduce the processing speed and increase the system complexity. In this paper we propose an all-optical signal processing system for performing the iterative algorithms by using a four wave mixing material which introduces a feedback loop in the system. We believe that this system may also be used as an optical two-dimensional dynamic memory device.
