Observation of Landau levels and topological edge states in photonic crystals through pseudomagnetic fields induced by synthetic strain
René Barczyk, L. Kuipers, Ewold Verhagen
The control over light propagation and localization in photonic crystals offers wide applications from sensing and on-chip routing to lasing and quantum light-matter interfaces. Wh…
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…
Cloaked near-field probe for non-invasive near-field optical microscopy
Felipe Bernal Arango, Filippo Alpeggiani, Donato Conteduca +7
Near-field scanning optical microscopy is a powerful technique for imaging below the diffraction limit, which has been extensively used in bio-medical imaging and nanophotonics. Ho…
Revealing the nanogeometry of WS2 nanoflowers by polarization-resolved Raman spectroscopy
Irina Komen, Sabrya E. van Heijst, Martin Caldarola +2
Recent studies of Transition Metal Dichalcogenides (TMDs) have revealed exciting optical properties like stable excitons and chiral light-matter interactions. Chemical vapor deposi…
Position-dependence of valley polarization and valley coherence of WS2 monolayer flakes
Irina Komen, Sabrya E. van Heijst, Sonia Conesa-Boj +1
Chiral interaction between light and two-dimensional transition metal dichalcogenides (2D-TMDs) has recently drawn enormous scientific attention. The optical selection rules of the…
