ABSTRACT:
A Faraday rotator in which a portion of a rare-earth iron garnet single crystal film is exposed to a localized magnetic field to control hysteresis. In one embodiment, the field is applied by a permanent magnet positioned on a part of the film. As a result, it is possible to fabricate Faraday effect optical switches and magneto-optical sensors using rare-earth iron garnet films having small saturated magnetic field intensities.
