Study on Electro-Optic Properties of One-Dimensional Photonic Crystals Band Structure
摘要: 采用有限元法对一维掺镧锆钛酸铅光子晶体的能带特性进行分析。当给一维掺镧锆钛酸铅光子晶体施以外加电场时，由于介质掺镧锆钛酸铅的电光效应引起折射率变化，使得一维掺镧锆钛酸铅光子晶体的能带结构发生变化。详细分析了外加电场变化对一维掺镧锆钛酸铅光子晶体的禁带结构特性的影响，禁带的中心波长及禁带宽度的变化量与电场呈四次函数关系。
Abstract: Using finite element method, the band-gap characteristics of one-dimensional (1D) PLZT photonic crystals is analyzed. When imposed by the applied electric field, the electrooptic effect of PLZT can cause change of its refractive index, and the band structure of 1D photonic crystals based on PLZT varies. The effect of the applied electric field on the band gap in 1D PLZT photonic crystals is analyzed in detail. And central wavelength and the change value of bandwidth is proportional to quadratic of electric field.
