State-of-the-art computational methods combined with common idealized structural models
provide an incomplete understanding of experimental observations on real nanostructures …

We numerically and experimentally demonstrate efficient light couplers between topological
slow light waveguides in valley photonic crystals (VPhCs) and wire waveguides. By …

We designed slow-light waveguides with a wide mode area based on slab-type valley
photonic crystal (VPhC) heterostructures which are composed of a graphene-like PhC …
