本文研究了介电布拉格反射镜之间夹有纳米复合层的一维光子晶体结构的透射谱和反射谱的主要特征。入射波的两个正交偏振对应于纳米复合材料的不同等离子体共振频率。如果其中一个等离子体激元频率与其中一个光子带隙中的缺陷模频率一致,就有可能完全抑制透射谱中的缺陷模,这使得这种结构的光谱对偏振敏感。
This paper examines the key features of the transmission and reflection spectra of a one-dimensional photonic crystal structure in which a nanocomposite layer is sandwiched between dielectric Bragg mirrors. Two orthogonal polarisations of an incident wave correspond to different plasmon resonance frequencies of the nanocomposite. If one of the plasmon frequencies coincides with the defect mode frequency in one of the photonic bandgaps, complete suppression of the defect mode in the transmission spectrum is possible, which makes the spectra of such structures polarisation-sensitive.
