Abstract
The electro-optical method described herein provides adjustable voltage dependent optical properties of a solid whereby the characteristics, i.e., the optical response to applied voltage, are separately adjustable for different laser frequencies. The solid has photo-absorbing centers capable of displaying persistent spectral hole burning; the spectral holes are capable of exhibiting electric-field induced filling. The main fields of application for this method are in integrated optics, image processing, and optical data storage.
