Non-Linear Magneto-Optic - Microwave Interactions : a New Range of Devices

Abstract
Ferrite films of yttrium-iron-garnet (YIG) are perfect candidates for various applications in microwave and infrared frequency range. The theoretical and experimental results of intense study of interaction of spin waves with light in such films are reviewed and practical applications are presented. Along with traditional methods of magneto-optic - spin wave interaction the novel methods including non-linear waves are considered. Traditional devices include frequency shifters, scanners, modulators, but a new class of non-linear devices is suggested and practical recommendations are provided.
