Ultrasensitive topological interface modes for refractive index sensing via all-dielectric one-dimensional photonic crystals

Abstract Topological interface modes (TIMs) are robust, localized states that emerge at the interface between two topologically distinct materials. In this work, the TIMs are studied in a broader frequency spectrum for both TE and TM polarizations using all-dielectric photonic crystal (PC) layers of...
