Preparation and Properties of One-Dimensional Magnetophotonic Crystals with Bi-Substituted YIG Films.

One-dimensional magnetophotonic crystals with bismuth-substituted yttrium iron garnet films were fabricated by a method that combines rf magnetron sputtering and pulsed-light annealing. The media exhibited significantly high transmittance and Faraday rotation at designated localized wavelengths of light in the photonic bandgap. These results coincide quantitatively with the theoretical prediction.
