| 摘 要： | 用传输矩阵法计算了两端对称缺陷复合光子晶体结构的光传输特性。计算结果表明:两端对称缺陷复合光子晶体D(AB)mD]2结构中的禁带出现两个完全共振透射峰。通过控制入射光强来微调光子晶体材料的介电常数,使得完全共振透射峰移动,且介电常数变化越大,共振透射峰偏移越大,从而形成高效率的双通道光开关。当光子晶体为D(AB)mD]N结构时,每个完全共振透射峰都分裂为N-1条,这样可通过调节N同时实现所需要通道数目的高效多通道光开关和多通道滤波器。

| Abstract: | By using the method of optical transfer maxtrix,the optical transmission properties of compound photonic crystal with two symmetrical defect layer at the two ports were studied.The investigation results showed that two resonance transmittance peaks exist in the band gap in dual-period photonic crystal D(AB)mD]2 structure.The resonance transmittance peaks will shift with the small changes of the dielectric constants of photonic crystal induced by a control light.The more the dielectric constants change,the ... |
