Abstract

Utilizing a form of tungsten oxide as the physical medium for optical memory, we show that infrared irradiation provides heat to the lattice structure while blue or blue-green light provides electronic excitation to initiate a photochromic chemical change. We have constructed and tested a spin stand based demonstration system for this form of optical memory. Tungsten oxide offers potential advantages in storage density, storage capacity, write speed, signal to noise, processing flexibility, data robustness, and overall, cost.
