In the review, peculiarities of spectra of one-dimensional photonic crystals made of anisotropic and/or magnetooptic materials are considered. The attention is focused on band gaps of a special type-the so called degenerate band gaps which are degenerate with respect to polarization. Mechanisms of formation and properties of these band gaps are analyzed. Peculiarities of spectra of photonic crystals that arise due to the linkage between band gaps are discussed. Particularly, it is shown that formation of a frozen mode is caused by linkage between Brillouin and degenerate band gaps. Also, existence of the optical Borrmann effect at the boundaries of degenerate band gaps and optical Tamm states at the frequencies of degenerate band gaps are analyzed.
在这篇综述中,考虑了由各向异性和/或磁光材料制成的一维光子晶体光谱的特性。注意力集中在一种特殊类型的带隙——所谓的简并带隙,它在偏振方面是简并的。分析了这些带隙的形成机制和特性。讨论了由于带隙之间的联系而产生的光子晶体光谱的特性。特别地,表明了冻结模式的形成是由布里渊带隙和简并带隙之间的联系引起的。此外,还分析了简并带隙边界处的光学玻恩曼效应以及简并带隙频率处的光学塔姆态的存在情况。
