Monolithic integration of a GaAlAs laser with a GaAs Schottky-gate field effect transistor is demonstrated. A GaAs field effect transistor with a 3-μm gate length is formed on a double-heterostructure laser crystal which is protected by a high-resistivity isolation layer. Laser light intensity is modulated to realize rise and fall times of less than 0.4 ns by modulating the field effect transistor gate voltage.
