Multichannel integrated optical modulator with strip GaAs–GaAs1–xPx waveguides

The results are given of the development and testing of an optical integrated circuit of a multichannel electrooptic modulator containing loaded optical strip waveguides formed in a base multilayer GaAs?GaAs1?xPx epitaxial structure. A report is given of the results of optimization of the parameters of the modulator and of the strip waveguides. An experimental value of the half-wave voltage for each modulator channel (~?24 V) is shown to agree well with the calculated value.
