Abstract

This paper discusses the fabrication and testing of on-chip photonic crystals in ferrite waveguides. Photonic bandgap engineering can produce Faraday rotators with highly enhanced polarization rotation for ultra-small integrated optical isolators. The main challenges to such devices are the elimination of linear birefringence and the fabrication of planar photonic bandgap nanostructures. These challenges are addressed in the present article. In particular, we demonstrate the presence of stopbands and resonant polarization response in single-defect magneto-optic photonic crystal ridge waveguides.
