Abstract
A new method to achieve periodic reversals of magnetization, necessary to attain high mode conversion efficiencies in magneto‐optic waveguides, is described. It is acomplished by means of a periodic Permalloy structure overlaying the optical propagation path. With proper bias fields, we have observed an optimum dc conversion efficiency of 80±2% at 1.15 μm in a Gd0.5Ga1 iron garnet film guide.Keywords
