摘要:

提出一种新型函数光子晶体, 其折射率为空间位置函数.  先由费马原理给出光在一维函数光子晶体中的运动方程,  推导后得到传输矩阵, 再给出一维函数光子晶体的色散关系、 带隙结构和透射率, 并通过选择不同折射率分布函数n(z)得到比常规光子晶体更宽或更窄的能隙结构.

关键词: 函数光子晶体, 透射率, 传输矩阵

Abstract:

The authors  proposed a concept of new function photon crystals, the  refractive index of which is a function of space position.  The light motion equation in one-dimensional function photon crystals was obtained by means of Fermat principle,  and  the transmission matrix was obtained via calculation, with  the dispersion relation, band gap structure and transmissivity given. The more wide and more narrow band gap structure than conventional photon crystals were obtained by choosing different distribution function n(z) of refractive index.

Key words: function photon crystals; , transmissivity; , transmission matix
