Abstract
Photonic crystals in magnetic materials open up a number of interesting possibilities for the study of nonreciprocal effects in confined geometries, including enhanced Faraday rotation and optical unidirectionality. The development of integrated devices based on nonreciprocal magneto-optic phenomena requires understanding the effects of geometrical confinement on light propagation and magnetization in these systems. This article introduces a model for controlling the band gap by exploiting the birefringence in film-based planar magneto-optic structures. It also presents a study of magnetic remanence control through magnetization confinement in the resonant microcavity of one-dimensional planar magnetophotonic crystals.
