Fabrication and characterization of a three-terminal self-aligned double-heterostructure optoelectronic switch in the light-emitting diode configuration are 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 energy of 0.02 fJ/μm2, an electrical switch-on transition of 4 ns is observed.
