MULTISTATE OPTICAL SWITCHING AND MEMORY USING AN AMPHOTERIC ORGANIC CHARGE TRANSFER MATERIAL

A multistate organic optical storage medium is disclosed, wherein an optical beam can switch any "data storage spot" on said optical storage medium into three or more memory states. The optical storage medium may consist of a mixture of bistate switching modules, or it may consist of large...

Zusammenfassung:	A multistate organic optical storage medium is disclosed, wherein an optical beam can switch any "data storage spot" on said optical storage medium into three or more memory states. The optical storage medium may consist of a mixture of bistate switching modules, or it may consist of large delocalized amphoteric molecules. The illuminated area of said optical storage medium will undergo an electrochemical topactic redox reaction which will cause certain moieties in the illuminated area to change oxidation state. By changing the intensity of the optical "write" beam the illuminated area can be switched to a plurality of specific states each state having a unique set of oxidation species. An optical/spectroscopic means is used to identify the presence of oxidation species and to "read" the data stored.
