Optoelectronic transient response of an n-channel double heterostructure optoelectronic switch

Abstract
A bistable n‐channel double heterostructure optoelectronic switch, fabricated as a three‐terminal light‐emitting diode, is reported and results are presented demonstrating simultaneous electrical and optical switching characteristics. Electrical turn‐on times of 2 ns are observed, with corresponding optical turn‐on times of 60 ns. Electrical turn‐off transition times of 6 ns are observed with optimum optical turn‐off times of 20 ns. These times are consistent with the device size and the measurement impedance.
