论文摘要
非热光子晶格将能量不保存的特殊后果与带结构的物理学结合在一起，从而产生了在常规材料或光子超材料中未发现的各种外来特性。在本教程中，我们介绍了非富米光光晶格的设计和实施中的关键概念，包括非富米特晶格汉密尔顿人及其bandinstructures的一般特征，非Hermitian lattice对称性的作用以及非Hermitian乐队结构的拓扑化学作用。我们调查了几种重要的非热晶格设计，以及可以实现的光子平台。最后，我们讨论了该领域未来发展的可能性。
Non-Hermitian photonic lattices combine the peculiar consequences of energy non-conservation with the physics of bandstructures, giving rise to a variety of exotic properties not found in conventional materials or photonic metamaterials. In this tutorial, we introduce the key concepts in the design and implementation of non-Hermitian photonic lattices, including the general features of non-Hermitian lattice Hamiltonians and their bandstructures, the role of non-Hermitian lattice symmetries, and the topological chracterization of non-Hermitian bandstructures. We survey several important non-Hermitian lattice designs, as well as the photonic platforms on which they can be realized. Finally, we discuss the possibilities for future developments in the field.
