摘要

我们设计了基于半导体的二维光子晶体，可以支持光线下的拓扑螺旋边缘态。我们用数值方法证明了在波导中，即使有尖锐的弯曲，边缘状态也能很好地引导光。该结构将为无辐射损耗的拓扑纳米光子波导提供新的平台。

Two-dimensional Topological Photonic Crystals with Helical Edge States below the Light Line

We design semiconductor-based two-dimensional photonic crystals that can support topological helical edge states below the light line. We numerically demonstrate that the edge states can guide light robustly in the waveguide even with sharp bends. The structure will be a new platform for topological nanophotonic waveguides with no radiation loss.
