Abstract

In the collinear interaction between magnetostatic waves and optical guided modes, the use of high microwave power is experimentally observed to broaden the range of microwave frequencies over which a significant optical mode conversion occurs. A mechanism contributing to this broadening is described that is based on a nonlinear shift in the wavelength of the magnetostatic waves at high power along with magnetic damping. Comparisons between previous experiments and our theoretical predictions show that this mechanism can explain some, but not all, of the changes observed in the optical spectrum at high microwave power levels
