Large‐Area Flat Optics Color Routing in Tilted Arrays of 2D Semiconductor Nanostripes

Advanced Optical Materials, EarlyView.
We develop a scalable flat optics platform exploiting self‐organised ion‐beam sputtering and maskless glancing‐angle deposition to fabricate centimetre‐scale arrays of tilted MoS2 nanostripes. The engineered geometry activates Rayleigh anomalies, guided modes, and Mie resonances, enabling highly directional color routing and enhanced light harvesting ...

Multiple Scattering Model for the Coherent Optical Response of Correlated Disordered Plasmonic Metasurfaces

Advanced Optical Materials, EarlyView.
Disordered plasmonic metasurfaces enable advanced control over light scattering through disorder engineering. A theoretical model based on multiple scattering theory is developed to predict the coherent reflection and transmission of light from disordered metasurfaces with arbitrary pair correlations.

Single Photon Emitters in Monolayer Semiconductors Coupled to Transition Metal Dichalcogenide Nanoantennas on Silica and Gold Substrates

Advanced Optical Materials, EarlyView.
Single‐photon emitters in WSe2 are formed at strain hotspots created by transition metal dichalcogenide (WS2) nanoantennas on dielectric and metallic substrates. Enhanced emission properties and collection efficiencies are achieved experimentally, while numerical optimization predicts fluorescence enhancements of more than four orders of magnitude ...

Breaking Optical Transparency and Electromagnetic Performance Trade‐Offs for Transparent Reflective Metasurfaces

Advanced Optical Materials, EarlyView.
A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without

Purely Equatorial Lasing in Spherical Liquid Crystal Polymer Microlasers with Bipolar Refractive Index Profile

Advanced Optical Materials, EarlyView.
Spherical liquid crystal polymer microlasers with a bipolar configuration confine lasing to a single equatorial plane, allowing precise control over where the laser emission is generated. The anisotropic refractive index profile additionally lifts the energy degeneracy of azimuthal whispering gallery modes, which causes a characteristic splitting into ...
