利用传输矩阵法，研究周期不对称度对光子晶体透射谱的影响，结果表明：当周期不对称度为零时，光子晶体透射峰随着周期数的增大而变得越精细，但其透射率均为100％不变；当周期不对称度为不等于零的恒定值时，光子晶体透射峰的透射率低于100％，但随着周期数的增大，透射峰仅变得精细而透射率不变；光子晶体透射峰的透射率随着周期不对称度增大而下降，而且不对称度越大，透射率下降越快，同时透射峰变窄的速度也越快。周期不对称度对光子晶体透射谱的影响规律，为光子晶体模型的构造和设计制备等提供方法依据。

The effect of periodicity asymmetry on photonic crystals transmission spectrum was studied with the transfer matrix method.The results showed that,when the periodicity asymmetry was 0 ,transmission peaks became sharper as the periodicity increased,but the transmittance was constantly equal to 1 0 0%;when the periodicity asymmetry was any constant and nonzero values,the transmittance was under 1 0 0%. On the other side,with the increasing of periodicity,the transmission peaks sharpened with a constant transmittance.The transmittance of transmission peaks decreased with the periodicity asymmetry increasing,and the greater asymmetry was the faster transmittance decreased,as well as the transmission peaks narrowed.These properties can provide a theoretical basis for the construction and preparation and design of the photonic crystals model.
