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

open access: yesAdvanced 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 ...

Wavelength‐Multiplexed 2D Beam Steering via a Passive Diffractive Network

open access: yesAdvanced Optical Materials, EarlyView.
Illustration of a wavelength‐multiplexed diffractive beam steering system, which is composed of K cascaded diffractive layers, each containing phase‐modulating elements that are jointly optimized using deep learning–based optimization. When illuminated with a set of wavelengths {λ1,λ2,…,λNw}$\{ {{{\lambda }_1},{{\lambda }_2},\ldots ,{{\lambda }_{{{N}_w}

Extrinsic Limitations of Stealthy Hyperuniform Devices

open access: yesAdvanced Optical Materials, EarlyView.
Stealthy hyperuniform devices exhibit a scattering‐free angular region whose extent follows a simple quenching equation. Experimental measurements confirm this prediction but reveal quenching efficiencies far below theoretical expectations. Multiple scattering and finite‐size effects are quantified, establishing realistic performance limits for ...

Aberrations‐Corrected Ratiometric Parameters and PLQYs for Upconversion Thermometry in Hexagonal NaYF4:Yb3+,Er3+ and NaYF4:Yb3+,Tm3+ in Micro and Nanoscale Phosphors Using Novel Integrating Sphere Setup

open access: yesAdvanced Optical Materials, EarlyView.
Each optical system introduces aberrations in the reading of photoluminescence, which makes the signal dependant on the lab equipment. Here, a calibrated system is used to obtain the PLQYs and ratiometric parameters of popular upconverters to be used in thermometry.
