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.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 Format 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 choosin~ different distribution fimetinn n（ ~,＇l nf r,~f,-~,-t;.,,~ ;.,-1,~.~
