Abstract

A thin-film waveguide Faraday rotator which provides nonreciprocal polarization rotation of ±45°for light of wavelength 1.45 μm with an extinction ratio of 500:1 has been demonstrated. This isolator structure makes use of laser annealing to reverse the sublattice magnetization and hence the sign of the Faraday effect in localized regions of a (Bi, Ga) yttrium iron garnet film. A novel geometrical pattern was designed for these regions to overcome the effects of the inherent thin-film birefringence.
