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…
Interplay of leakage radiation and protection in topological photonic crystal cavities
René Barczyk, Nikhil Parappurath, Sonakshi Arora +3
The introduction of topological concepts to the design of photonic crystal cavities holds great promise for applications in integrated photonics due to the prospect of topological…
Breakdown of spin-to-helicity locking at the nanoscale in topological photonic crystal edge states
Sonakshi Arora, Thomas Bauer, Nikhil Parappurath +3
We measure the local near-field spin in topological edge state waveguides that emulate the quantum spin Hall effect. We reveal a highly structured spin density distribution that is…
Direct quantification of topological protection in symmetry-protected photonic edge states at telecom wavelengths
S. Arora, T. Bauer, R. Barczyk +2
Topological on-chip photonics based on tailored photonic crystals (PhC) that emulate quantum valley Hall effects has recently gained widespread interest due to its promise of robus…
