Paper Abstract

In this paper the most recent advances on noncollinear guided-wave magnetooptic (MO) Bragg interactions in which the light waves propagate in directions nearly orthogonal to that of the magnetostatic waves, the resulting MO Bragg cells, and two applications are given. First, the basic interaction geometry and underlying physical mechanisms, and the realization of wideband MO Bragg cells in pure and Bismuth-doped YIG-GGG waveguides for the carrier frequencies ranging from 2 to 12 GHz are presented. Applications of the wideband MO Bragg cells to light beam scanning and real-time spectral analysis of microwave signals are then described. Finally, comparative advantages and disadvantages of guided-wave MO Bragg cells versus their acoustooptic (AO) counterparts are discussed.
