摘要
拓扑光子学被认为是设计纳米光子器件的稳健而灵活的平台,可防止结构缺陷和性能下降。光子晶体(PhC)激光器与基于空间分布增益和损耗的奇偶校验-时间(PT)对称系统相结合,为纳米光子结构中的激光模式竞争和拓扑保护提供了理想的试验平台。在这项研究中,使用由耦合纳米谐振器组成的 Su-Schrieffer-Heeger 晶格的 PhC 激光器演示了单拓扑边缘模式 (TEM) 激光。通过诱导定向损耗控制,实施了一种模式选择策略,实现了边模抑制比超过 30 dB 的单 TEM 激光。其中一个 TEM 对额外损耗通道引入的局部电势变化表现出显著的鲁棒性。这种将拓扑保护和 PT 对称性整合到纳米光子学中的策略,将为开发不受纳米光子集成电路输出通道干扰的片上单模拓扑激光器开辟新的前景。
Topologically Protected Single Edge Mode Lasing in Photonic Crystal Su–Schrieffer–Heeger Lattice with Directional Loss Control
Topological photonics is considered to be a robust and flexible platform for the design of nanophotonic devices against structural imperfections and performance degradation. Combining with parity-time (PT) symmetry systems based on spatially distributed gain and loss, photonic crystal (PhC) lasers with micron-size carrier reservoirs offer an ideal test bed for lasing mode competition and topological protection in nanophotonic structures. In this study, single topological edge mode (TEM) lasing is demonstrated in PhC lasers with a Su–Schrieffer–Heeger lattice comprised of coupled nanoresonators. By inducing directional loss control, a mode selection strategy is implemented, that achieves single TEM lasing with a side-mode-suppression ratio exceeding 30 dB. One of the TEMs exhibits remarkable robustness against local potential variation introduced by additional loss channels. This strategy integrating both topological protection and PT symmetry in nanophotonics would open up new prospects for the development of on-chip single-mode topological lasers unperturbed by output channels in nanophotonic integrated circuits.
