摘要

我们研究了特别设计的拓扑光子晶体，使得频率带隙出现在ω 0,2 ω 0,3 ω0附近，更重要的是，每个带隙恰好包含一个单向边缘模式。然后利用这些单向边缘模式来实现关键的非线性频率混合过程，例如二次谐波和三次谐波的产生。

Frequency mixing in nonlinear interaction of one-way edge-modes of topological photonic crystals

We investigate topological photonic crystals specially designed such that the frequency band gaps appear around ω0, 2ω0, 3ω0 and, more importantly, each band gap contains exactly one unidirectional edge mode. These one-way edge modes are then utilized to implement key nonlinear frequency mixing processes, such as second- and third-harmonic generation.
