Abstract :
A specific expression for the efficiency of guided-wave magnetooptic (MO) Bragg diffraction by magnetostatic backward volume waves (MSBVWs) in an yttrium iron garnet-gadolinium gallium garnet (YIG-GGG) waveguide structure is derived. Numerical analysis on the effects of DC magnetic field and geometrical characteristics between the MSBVW- and magnetostatic forward volume wave (MSFVW)-based MO Bragg cells are presented. Application of the MSBVW-based MO Bragg cells to real-time spectral analysis of microwave signals has also been demonstrated
