<p>Optical devices using an organic charge transfer salt as the switching and storage media. Generally, a light beam (26) of a given intensity directed to a film of certain organic charge transfer salts (20) causes the illuminated area (28) to change from a first to a second state. This electrochemical process is reversible with heat energy transforming the illuminated area (28) back into the first state. The first and second states have identifiably different optical and electrical properties. The organic charge transfer salt is used to fabricate an erasable or permanent optical memory and a threshold on bistable optoelectronic switch. </p> |
