Abstract

The realization of high-performance magnetostatic backward volume wave (MSBVW)-based magnetooptic (MO) Bragg cells in pure and bismuth-doped yttrium iron garnet-gadolinium gallium garnet (YIG-GGG) waveguides is discussed, and the demonstration of wide-angle light beam scattering using such MO Bragg cells is reported. The MSBVW-based MO Bragg cells have been shown to possess the following advantages over the magnetostatic forward volume wave (MSFVW)-based counterparts: (1) the center frequency of the former is higher by some 4.9 GHz at the same DC magnetic field; (2) the first passband in which the MO Bragg cells commonly operate is located at the high-frequency end for the former, but at the low-frequency end for the latter; and (3) the Bragg diffraction or mode-conversion efficiency of the MSBVW-based MO Bragg cells can be significantly higher than that of the MSFVW-based counterparts.<>
