A Multi‐Resonant Tunable Fabry‐Pérot Cavity for High Throughput Spectral Imaging

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study introduces a multi‐resonant tunable Fabry‐Pérot filter for high throughput spectral imaging. With a spectral resolution of 10 nm and a switching time of 23 ms, this compact and low‐cost device possesses better spectral imaging accuracy in poor light conditions while maintaining over six times higher optical throughput than standard liquid ...

Fabrication and Optical Characterization of CMOS‐Compatible Honeycomb‐Like Large‐Scale Lattices of Near‐Field Coupled Plasmonic TiN Nanotriangles

open access: yesAdvanced Optical Materials, EarlyView.
Honeycomb‐like plasmonic titanium nitride nanotriangle arrays are fabricated in a complementary metal‐oxide‐semiconductor pilot line. Experimental and simulated reflectances as a function of energy and in‐plane momentum match a dispersion relation based on nearest‐neighbor dipole coupling, this indicates Diract points at the K point.

Angle‐ and Polarization‐Tolerant Metasurface Designs Based on the Aperiodic Tiling

open access: yesAdvanced Optical Materials, EarlyView.
A novel aperiodic metasurface design is introduced to mitigate the inherent angle and polarization sensitivity of conventional metasurfaces. By employing a recently discovered aperiodic tiling approach, identical elliptical scatterers are arranged with systematic variations in their spacing and orientation, effectively minimizing spectral reflectance ...
