Abstract
A new design of GaAs/AlGaAs waveguide amplitude modulator intended for array applications at 830nm wavelength is reported. The device is based on polarization rotation and has bandwidths in excess of 1 GHz and an extinction ratio of 1 7dB. Mach-Zehnder modulators with 23dB have also been fabricated and arrays with 20 microns device separation fabricated. The arrays have crosstalk less than -20dB and feature electrical interconnection compatible with standard packaging techniques.Keywords
