Double heterostructure optoelectronic switch as a dynamic memory with low-power consumption

Abstract

A pnn double heterostructure optoelectronic switch with dual extractor electrodes was dynamically operated as an optical memory with the resulting achievement of 20 μW holding power. This value represents a reduction in holding power of about three orders of magnitude as compared to that of conventional light-emitting optical bistable devices. Complete operation, involving optical writing, regeneration, and high-speed erasing of written data through a dual extractor-electrodes configuration, was carried out with a simple driving scheme.
