<title>Erasable-dye-polymer-based optical neural network</title>

Abstract

The search for a dynamic recording medium that can be used in real time without the need for processing has become a critical issue in the development of practical neural network systems, correlators, all-optic switches, image and signal processors, and optical storage (including 3-D) devices. A typical optical material responds to changes in the intensity, polarization, or wavelength of the illuminating light. The optical material developed and used for neural network applications responds to changes in the polarization of blue or green laser (Ar+) light. Implementing a neural network or performing opticallycontrolled acoustic beam steering requires a high-speed read/write/erase optical memory. POC's erasable dye polymer (EDP) material offers a high read/write/erase data rate, nondestructive reading, fast data access, high storage density, overwrite capability, and long cycle life.
