Abstract

An AlGaAs/GaAs double heterostructure light emitting diode (LED) and a GaAs field effect transistor (FET) have been monolithically integrated on a GaAs substrate using a combination of liquid phase and molecular beam epitaxies. The electrical isolation between LED and FET has been achieved by inserting a molecular beam-grown high resistivity AlGaAs layer. A linear gate voltage-to-light power transfer characteristic with a 13 ns time constant has been demonstrated.
