光子绝缘体中的一系列杂质单元引入了在窄频带上保持的电磁杂质模式。我们引入了一个模型，这个带的方式紧束缚描述的杂质带在半导体中，并用它来描述波导沿着链，特别是，在一个角落的90度。我们还指出了利用光子绝缘体中的杂质带来研究波沿沿着一维无序链传播的可能性。[S0163-1829（98）11919-7]。
A chain of impurity cells in a photonic insulator introduces impurity modes of the electromagnetic held over a narrow band of frequencies. We introduce a model of this band in the manner of a tight-binding description of impurity bands in semiconductors, and use it to describe waveguiding along the chain, and, in particular, across a corner of 90 degrees. We also point out the possibility of using impurity bands in photonic insulators to study wave propagation along an effectively one-dimensional disordered chain. [S0163-1829(98)11919-7].
