摘要光子晶体凭借其优异性能和广阔的应用前景,近年来成为国内外研究人员争先研究的热点,有关其的理论分析方法、制备方法及新型光电器件不断涌现。而其最显著的特点就是光子带隙,处于光子带隙中的光不能在光子晶体中传播。而引入缺陷后,在带隙中形成缺陷态,利用这种特性形成许多新型光电器件。61561

Title Optical microcavity based on photonic crystal slab
Abstract With its excellent performance and broad application prospects, Photonic crystal become a hot research on which researchers at home and abroad concentrate in recent years. Theoretical analysis, preparation methods and new optoelectronic devices about photonic crystal microcavity are emerging. And its most outstanding feature is the photonic band gap. The light in the photonic band gap can not propagate in the photonic crystal. If defects are introduced, the defect states will be permitted in the band gap, which can be used to create many new optoelectronic devices.
It describes the photonic crystal historical background and research status, explains its theoretical basis, using the plane wave expansion method, finite difference time domain method on a computer-based planar photonic crystal optical microcavity structure and properties of the simulation, with reference to previous photonic crystal microcavity merits further by optimizing the microcavity structure design to improve the quality factor of microcavities.
