Enhanced Faraday and nonlinear magneto-optical Kerr effects in magnetophotonic crystals

The fabrication of magnetophotonic crystals (MPC) composed from Bi-substituted yttrium-iron-garnet films separated by silicon oxide layers is presented. The enhancements of the Faraday rotation, second-harmonic generation and nonlinear magneto-optical Kerr effect are observed at the photonic band gap edge. These demonstrate strong light-matter magnetic coupling in MPC and provide the prospects of the new magneto-optical materials for applications. [Copyright &y& Elsevier]
