摘要:

为得到响应时间较短的全光开关,在光子晶体的所有高折射率层掺入Kerr介质,基于Kerr非线性效应导致的禁带整体移动原理,设计了两种一维光子晶体全光开关结构。应用时域有限差分(FD-TD:Finite Difference-Time Domain)法,编制Matlab计算程序,对全光开关进行数值特性分析。讨论频率混合效应对全光开关的影响。观察光子局域效应增强光子晶体非线性的现象,验证光子局域效应与光子晶体完整周期结构的层数有关,层数太少光子局域效应不明显。

关键词: 光子晶体, 全光开关, 非线性, 频率混合, 光子局域

Abstract:

To obtain a shorter response time, all-optical switch, in a photonic crystal high refractive index layers all mixed Kerr medium, based on the Kerr nonlinear effect caused by the whole band moving principle, design of the two kinds of one-dimensional photonic crystal all-optical switch. Application of FD-TD(Finite Difference-Time Domain) method, the preparation of Matlab computer program, for all-optical switching characteristics of numerical analysis. Discuss the frequency of mixed effects on the all-optical switching effects. Observation of photon localization effect of photonic crystals to enhance nonlinear phenomena, verify photon localization effect and photonic crystal structure of a complete cycle of the relevant number of layers, number of storeys photon localization effect was not obvious enough.

Key words: photonic crystals, all-optical switching, nonlinearity, frequency mixing, photonic localization
