Abstract
Embodiments of a magneto-optic crystal assembly for use in polarization rotation applications are disclosed. In one aspect, a magneto-optic crystal assembly includes two or more magneto-optic crystals. The temperature and wavelength dependencies of Faraday rotation of these crystals are compensated so that the crystal assembly has both reduced temperature and wavelength dependencies of the polarization rotation angle over broad temperature and wavelength ranges.
