Nonlinear one-way edge-mode interactions for frequency mixing in topological photonic crystals

Abstract
Unlike solid-state physics, the common test bed for new ideas in topological physics, topological photonics provides an ideal platform to study nonlinear wave interactions. Here, the authors investigate nonlinear interactions of one-way edge modes in frequency mixing processes in topological photonic crystals and demonstrate that more exotic phenomena, such as slow-light enhancement of nonlinear interactions and harmonic generation upon interaction of backward-propagating edge modes, can also be realized. This paper paves the way for the investigation of topology-protected frequency mixing processes in photonics.
