The storage of information in the time domain through the use of spectral hole burning rare‐earth‐doped crystals is described. The technique, which is also known as stimulated echo, makes serial read/write data rates of 100 MHz possible. Applications include high‐speed memory, signal processing, high‐speed optical switching, optical interconnects, image processing, and logic operations.
