Abstract
An optoelectronic memory, logic, and interconnection device having an optical bistable circuit as an essential element. The optical bistable circuit includes an optical bistable switch which is a light emitting device and a first phototransistor detecting the light emitted from the light emitting device, connected in series, a second phototransistor connected in parallel to the optical bistable switch which does not detect the light emitted from the light emitting device, and a load resistor connected in series to the optical bistable switch. The optoelectronic memory, logic, and interconnection device operates as an optoelectronic memory device turned on and off with the same light source, as an optoelectronic logic device executing exclusive OR operation, or as a light source for reconfigurable optical interconnection.
