单负材料光子晶体微腔的光学双稳态
Study of Optical Bistability of Photonic Crystal Microcavity Composed of Single Negative Materials
摘要
Abstract
In the periodic structure that consists of two kinds of single negative materials, there is an omnidirectional reflectivity that has nothing to do with the lattice parameter and polarization state. If there is a defect in the periodic structure, the localized mode with higher quality factor will appear in the bandgap. The effects of the thickness of the defect layers on the localized mode and its electric field distribution of the localized mode are studied. If the defect layer is nonlinear Kerr medium, the optical bisability is deduced. After introducing a frequency modulation value S, the optical bisability depends on the & and structure parameters, not on the kinds of microcavity structure. The critical value of the frequency modulation to produce the bistability is 0. 866.关键词
