Successful fabrication of high performance microlenses and microlens arrays using the titanium-indiffusion and proton-exchange technique has enabled realization of a variety of integrated electrooptic Bragg modulator modules in the LiNbO3 channel-planar composite waveguides of 0.2- × 1.0- × 1.8-cm3 substrate size. These integrated optic device modules have been utilized successfully to perform matrix–vector and matrix–matrix multiplications. Through the channel-waveguide and the linear microlens arrays, the very large channel capacities that are inherent in the diode laser and the optical fiber as well as the photodetector arrays may be conveniently exploited. Consequently, such integrated optic device modules should facilitate realization of multichannel optical computing as well as communication and rf signal processing systems.
