Broadband localization of light at the termination of a topological photonic waveguide
Daniel Muis, Yandong Li, René Barczyk +4
Localized optical field enhancement enables strong light-matter interactions necessary for efficient manipulation and sensing of light. Specifically, tunable broadband energy local…

Impact of transforming interface geometry on edge states in valley photonic crystals
Di Yu, Sonakshi Arora, L. Kuipers
Topologically protected edge states arise at the interface of two topologically distinct valley photonic crystals. In this work, we investigate how tailoring the interface geometry…

Multiple backscattering in trivial and non-trivial topological photonic crystal edge states with controlled disorder
S. Arora, T. Bauer, R. Barczyk +2
We present an experimental investigation of multiple scattering in photonic-crystal-based topological edge states with and without engineered random disorder. We map the spatial di…
