摘要
为了研究一维各向异性光子晶体的全反射隧穿偏振特性,利用传输矩阵法计算了TE波和TM波以大于全反射角入射一维各向异性光子晶体时的透射率,在透射波中发现了TE波和TM波的一、二级全反射隧穿带.得出了与一维各向同性光子晶体的全反射隧穿效应的不同点,即TE波和TM波的一、二级全反射隧穿带的频率中心和频率宽度存在着较大的差异,利用这个特性可以将两种偏振光进行频率分离,为设计优质偏振滤波器提供理论依据.
For studying polarization properties of total reflection tunnel effect of 1D anisotropic photonic crystal,the transition matrix method is adopted,and the transmissivity of TE wave and TM wave are studied when incident angle greater than full reflection angle.1 grade and 2 grade total reflection tunnel effects are found in the transmission wave.Some new properties of total reflection tunnel effect of 1D anisotropic photonic crystal are btained.Tunnel frequencies of TE wave and TM wave have great differences,and this feature can be achieved using frequency separation of TE wave and TM wave,which can be used in the design of high-quality polarizing filter.
