Magneto-Optic Effects at 1.15 micrometer In Gd(.5)Y(2.5)Ga(1) Iron Garnet Thin Film Waveguide

Abstract

Two (Gd(.5)Y(2.5))(Fe(4)Ga(1))O(12) garnet films deposited on GGG substrates have been tested for possible use as modulators, switches and isolators. Their passive optical waveguiding properties have been characterized at a wavelength of 1.15 micrometer. Modulation of the output, passed through an analyzer, was observed by applying a longitudinal magnetic field. The mode conversion efficiency was shown to be limited primarily by the phase velocity mismatch between TE and TM modes. The possibility of phase modulation of TM modes by a transverse magnetic field is discussed in the light of data obtained in the mode conversion experiments.
