Efficient coupling of topological photonic crystal waveguides based on transverse spin matching mechanism

Efficient coupling of topological photonic crystal waveguides based on transverse spin matching mechanism

Abstract Topological photonic structures have great potential to revolutionize on-chip optical integration due to the merit of robust propagation. However, an equally important issue, i.e., the efficient input and output coupling of topological structure with other elements, has not been systematica...
