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…

Substrate-Induced Chirality in an Individual Nanostructure
Sergey Nechayev, René Barczyk, Uwe Mick +1
We experimentally investigate the chiral optical response of an individual nanostructure consisting of three equally sized spherical nanoparticles made of different materials and a…

Vectorial vortex generation and phase singularities upon Brewster reflection
René Barczyk, Sergey Nechayev, Abdullah Butt +2
We experimentally demonstrate the emergence of a purely azimuthally polarized vectorial vortex beam with a phase singularity upon Brewster reflection of focused circularly polarize…
