Experiments have been carried out in order to investigate the interaction of optical waveguide modes with spin waves in yttrium-iron-garnet films. The waves were excited using an array of copper wire antennas placed 4 mm apart. The light source for the experiments was a He + Ne laser operating at a wavelength of 1.15. In order to study the mode conversion of the optical waveguide, the excitation antenna was fed a microwave signal which was modulated in amplitude by a meander of 1 kHz. The output signal from the photodiode was measured as a function of the microwave input power for mode conversions TM(0) and TE(0). Over the range of microwave input powers investigated, the mode conversion behavior was found to be linear. The maximum conversion coefficient was 0.04 percent. The applications of iron-garnet films in integrated optics and spin-wave electronic devices are discussed. 5 references.
