Direct quantification of topological protection in symmetry-protected photonic edge states at telecom wavelengths
Abstract Topological on-chip photonics based on tailored photonic crystals (PhCs) that emulate quantum valley-Hall effects has recently gained widespread interest owing to its promise of robust unidirectional transport of classical and quantum information. We present a direct quantitative evaluation...
