Abstract

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.
