摘　　要：运用传输矩阵方法研究了材料色散对传统周期结构一维光子晶体光子带隙的影响.计算结果表明,考虑色散后,光子带隙既可能变窄也可能增宽,既可能发生红移也可能发生蓝移.光子带隙的改变与色散材料的色散强度、谐振频率及2介质材料折射率差的改变相关.色散强度越大对光子带隙的影响也越大.一般来说,若考虑色散后两介质材料的折射率差增大,则光子带隙增大,反之减小.所得结论可为相关光子器件的设计提供参考.By means composed of disper are discussed. It is shift or blue shift parameters such as refra of th incre consi of transfer matrix method, the bandgap properties of one-dimensional photonic sive and non-dispersive materials with the traditional periodic dielectric microst shown that the material for the photonic band strength of dispersive, dispersion gap. These damping coe bring about narrowness or enlargement, crystals ructures and red changes are related with the dispersive medium fficient, resonance frequency and the change of the ctive index difference of two dielectric materials. The larger the dispersive e photonic bandgap will have. As a whole, the width of photonic bandgap ase of refractive index difference of two dielectric materials which t dered. These work can be a useful reference for the design of related phot intensity, the more chang become increasing with th he material dispersion i onic devices.
