摘要
用传输矩阵法(TMM)研究了由SiO2和TiO2组成的一维光子晶体微腔的放大特性和耦合腔光子晶体的滤波特性。结果表明:在微腔光子晶体的缺陷层中掺杂一定浓度的Er+3,则对中心波长λ0=1.532μm,可以实现光放大;而二耦合腔或三耦合腔光子晶体可以作为二波长或三波长的滤波片。
The Amplification characteristics of one dimensional photonic crystal micro-cavity and the filtering characteristics of one dimensional photonic crystal coupled-cavity are studied by using the transfer matrix method. The results show that the central wavelength of λ0 = 1. 532 um can be amplified in the erbium doped photonic crystal micro-cavities ;and that it is possible to filter 2 or 3 waves using 2-CC or 3-CC photonic crystal.
