Optically induced switching in a p-channel double heterostructure optoelectronic switch

Abstract
The switching time of a double heterostructure optoelectronic switch is investigated using an optical input. A switch‐on time of 5–10 ps is obtained using a discrete microwave package. The fall time of 10 ns is limited almost totally by the parasitic capacitance of the package. The switching operation shows the unique ability to turn on and off with the incident optical signal.
