Tunable Topological Valley States in the Ge2Sb2Te5-based Photonic Crystal

We propose a Ge2Sb2Te5-based photonic crystal to tune topological valley states dynamically, where the center frequency shifts from 202.19THz to 133.36THz, and serves as an efficient switch to control the broadband light transport on chips.
