WebApr 8, 2024 · Nature Communications. Pseudo-spin and valley degrees of freedom engineered in photonic analogues of topological insulators provide potential approaches to optical encoding and robust signal transport. Here we observe a ballistic edge state whose spin–valley indices are locked to the direction of propagation along the interface between … WebDec 11, 2007 · One-way edge modes in a photonic crystal of semiconductor at terahertz frequencies. Electromagnetic edge mode in a photonic crystal (PhC), which is a square array of semiconductor rods in air, is theoretically investigated for terahertz frequencies and can be immune to backscattering at large defect on the wavelength scale and 90° sharp bend.
