High density waveguide modulator arrays for parallel interconnection

Conference Paper

A new design of GaAs/AIGaAs 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 1GHz, and an extinction ratio of 17dB. 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.
