论文摘要
拓扑光子学最近被证明是操纵光的强大框架。尤其是，主动拓扑光子系统通过采用非线性光 - 物质相互作用，从而使更丰富的基本物理能够为拓扑激光等应用打开新的景观。在这里，我们报告了一种基于拓扑不同的kagome光子晶体形成的半导体腔的全dilectric拓扑绝缘体激光器。提议的平面半导体Kagome晶格允许电信区域的光子谷效应在光线下方的宽带边缘状态，该效应是电信区域的光子谷效应，该效应提供了一种新的途径来检索非平凡的光子拓扑并为可靠的光生成和运输开发集成的拓扑系统。
Topological photonics has recently been proved a robust framework for manipulating light. Active topological photonic systems, in particular, enable richer fundamental physics by employing nonlinear light-matter interactions, thereby opening a new landscape for applications such as topological lasing. Here we report an all-dielectric topological insulator laser scheme based on semiconductor cavities formed by topologically distinct Kagome photonic crystals. The proposed planar semiconductor Kagome lattice allows broadband edge states below the light line due to photonic valley hall effect in telecommunication region, which provides a new route to retrieve nontrivial photonic topology and to develop integrated topological systems for robust light generation and transport.
