Abstract

The prospects for realization of Lithium Niobate (LiNbO₃) -based integrated optic (IO) devices and modules for applications in RF signal processing and communications have already been firmly established. For example, the planar waveguide acoustooptic (AO) Bragg cells are now widely used in the development of IO modules for spectral analysis and correlation of wideband RF signals. A variety of electrooptic (EO) devices that utilize parallel channel waveguides and crossed channel waveguides have also been developed into compact modules for wideband communications and switching as well as high-speed analog to digital conversion of RF signals. While advancements on the IO device modules for communications and signal processing are continuing, serious attemps on realization of device modules for computation of both analog and digital data have also been started recently (1-4).
