我们从理论上证明了光子晶体的非透射频率范围可以通过使用多个异质结构而被大大扩展。这种光子多重异质结构由不同的光子晶体组成。光子晶体的组成被选择为使得相邻组成的非透射频率范围以类似于半导体异质结构中的带隙的II型排列的方式排列。用传递矩阵法对二维系统中的例子进行了理论论证。
We show theoretically that the nontransmission frequency range of photonic crystals can be substantially enlarged as desired by using multiple heterostructures. This photonic multiple heterostructure consists of different photonic crystals. The constituent photonic crystals are chosen such that the nontransmission frequency ranges of the adjacent constituents are arranged in a way similar to the type-II lineup of the band-gaps in semiconductor heterostructures. Examples in the two-dimensional systems are demonstrated theoretically by using transfer matrix methods.
