摘要

拓扑光子学是一个新兴且快速发展的领域，研究光的拓扑相和拓扑绝缘体。最近，通过引入非空间自由度，这些系统的范围急剧扩大。这些合成尺寸的范围可以从波导阵列的腔模式或布洛赫模式的离散梯形到脉冲系统中的时间仓划分（离散时间步长），甚至到诸如晶格常数的参数。将空间维度和合成维度相结合，提供了观察基本和奇异现象的可能性，如四维或更高维度的动力学、与无序的长程相互作用、高维非线性效应等。在这里，我们回顾了使用非空间维度作为增强光子拓扑系统基本特征的手段的最新进展，并试图确定下一个挑战。c©2021美国光学学会

Topological photonics in synthetic dimensions

Topological photonics is a new and rapidly growing field that deals with topological phases and topological insulators for light. Recently, the scope of these systems was expanded dramatically by incorporating non-spatial degrees of freedom. These synthetic dimensions can range from a discrete ladder of cavity modes or Bloch modes of an array of waveguides to a time-bin division (discrete time steps) in a pulsed system or even to parameters such as lattice constants. Combining spatial and synthetic dimensions offers the possibility to observe fundamental and exotic phenomena such as dynamics in four dimensions or higher, long-range interaction with disorder, highdimensional nonlinear effects, and more. Here, we review the latest developments in using non-spatial dimensions as a means to enhance fundamental features of photonic topological systems, and we attempt to identify the next challenges. c © 2021 Optical Society of America
