A progress report on wideband magnetooptic interactions between guided-optical waves and magnetostatic waves, the resulting device modules, and applications to communications and signal processing is given. First, the technique for realization of GHz-bandwidth magnetooptic Bragg cells with electronically tunable center frequency (from 2.0 to over 11.0 GHz) and their applications to wideband light-beam scanning and switching, and RF spectral analysis are described. The design, fabrication, and performance characteristics of ion-milled waveguide lenses and the resulting magnetostatic wave-based integrated-optic device modules are then presented.
