摘　　要：通过传输矩阵方法,研究了含各向异性左手材料的一维光子晶体耦合微腔结构。结果表明,该结构中存在两类微带,一类位于常规的Bragg带隙,另一类位于零均值折射率带隙。当腔的厚度发生调制时,两类微带变成两类Wannier-Stark态。耦合微腔厚度梯度因子增大时,两类带隙中Bragg振荡周期都减小,而且透过率降低。One dimension photonic crystal coupled microcavity structure with anisotropic left handed materials is investigated by means of the transfer matrix method.It is shown that two kinds of minibands are formed in the structure.One is conventional Bragg miniband,the other is zero mean refractive index miniband.When modulating the thickness of the cavity,two type minibands turn into two type of Wannier-Stark ladder.The transmission and period of oscillation are found to decrease with the increasing gradient factor.
