Optoelectronic Transient Response of the Self-Aligned Double Heterostructure Optoelectronic Switch

Fabrication and characterization of a three terminal self-aligned Double heterostructure OptoElectronic Switch in the light-emitting diode configuration, is reported. Results demonstrating device switching characteristics are presented, in which switching is triggered by electrical or optical stimuli. Electrical switch- on and switch-off transitions occur in 10 ns, under electrical stimulus. Corresponding optical turn-on times of 60 ns are observed. With an optical switching of 0.02 fJ/microns m sup 2 an electrical switch-on transition of 6ns is observed.
