Abstract:
1. An optoelectronic memory device, comprising: an information-storage medium that includes an information-storage layer that can be locally and reversibly switched between at least two optical states by application of electrical fields to rotatable molecular components contained therein; a detector layer within the information-storage medium that can detect whether or not an applied electromagnetic radiation beam is transmitted through the information-storage medium at different positions of the information-storage medium; and a read/write device that applies electrical fields to write information into the information-storage layer and that applies electromagnetic-radiation beams in order to read information stored in the information-storage layer; and wherein the information-storage layer comprises a two-dimensional optical state-change organic polymer having a relatively rigid, fused-ring, organic-dye-based planar network and acetylene-linked rotatable molecular components.
