论文摘要
拓扑角状态（TCS）和拓扑边缘状态（TES）提供了控制光传播的新方法。基于TCS和TES的拓扑耦合型腔体波导系统（TCCWS）的构建值得期待，因为它在实现高性能微纳米集成光子设备方面的研究前景。在这封信中，与常规的耦合腔 - 波基指导系统（CCCWS）相比，在二维（2D）光子晶体（PC）中提出了TCCW。这项工作将提供设计高性能逻辑门，激光器，过滤器和其他微纳米集成光子设备并扩展其应用程序的可能性。
Topological corner state (TCS) and topological edge state (TES) have provided new approaches to control the propagation of light. The construction of topological coupled cavity-waveguide system (TCCWS) based on TCS and TES is worth looking forward to, due to its research prospects in realizing high-performance micro-nano integrated photonic devices. In this Letter, TCCWS is proposed in two-dimensional (2D) photonic crystal (PC), which possesses strong optical localization, high quality factor and excellent robustness compared with the conventional coupled cavity-waveguide system (CCCWS). This work will provide the possibility to design high-performance logic gates, lasers, filters and other micro-nano integrated photonics devices and expand their applications.
