ABSTRACT:
A CCD driven integrated optical modulator array including an array of chirp grating optical lenses implemented on the surface of an electro-optical crystal such as LiNbO.sub.3 or LiTaO.sub.3, a plurality of channel waveguides and a thin metal film pattern on the surface of the waveguides for modulating the optical waveform in each channel. The thin metal film form planar capacitors, each of the capacitors being electrically connected to the output circuit of a corresponding semiconductor device, such as a CCD array. The CCD array is implemented on a semiconductor wafer bonded to the electro-optical crystal. Signals in each optical channel in the electro-optical crystal are thereby modulated by corresponding circuit elements associated with corresponding CCD channels implemented on the major surface of the semiconductor wafer.
