Microwave signals modulate optical signals in unit integrable with GaAs and GaAIAs devices. Experimental GaAIAs electro-optical modulators designed and built for operation at wavelength of 0.82 micrometers. Easily integrable with GaAs monolithic microwave integrated circuits. Integrated optical and microwave waveguides in electro-optical materials constitute traveling-wave electro-optical modulator in configuration of Mach-Zehnder interferometer. Because characteristic impedance of waveguide 50 ohms - standard value - no impedance-matching network required.
