Abstract

A high-density, high speed dynamic optical memory technique based on two-photon coherence excited spin echoes in a spectral hole-burning medium was described. The advantage of this technique was the potential for high-temperature operation over conventional echo-based spectral hole-burning memory. It was shown that the write window was determined by the spin, which was longer than the optical spin at higher temperatures. The results showed the potential of higher capacity optical data storage than by conventional photon echo memories in rare-earth doped solids at high temperatures.
