Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters

Advanced Functional Materials, EarlyView.
An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Pixel-level spectrally programmable organic light-emitting diodes enabling hyperspectral reconstruction

PhotoniX
Hyperspectral imaging has long been constrained by inherent trade-offs among spatial, spectral, and temporal resolutions, as well as by limited optical throughput and reliance on complex micro-nano fabrication processes.

Exceptional Electro‐Optic Coefficient Unlocked via Polarization Swaying in KNbO3 Thin Films

Advanced Functional Materials, EarlyView.
We present the largest reported electro‐optic response in any material to date, guided by a new design principle that exploits ultralow coercive field polarization swaying enabled by low‐symmetry ferroelectric phases in monoclinic KNbO3 thin films for energy‐efficient classical and quantum photonic integrated circuits. ABSTRACT The electro‐optic effect

Passive sensing around the corner using spatial coherence

Nature Communications, 2018
Non-line-of-sight sensing requires purposely controlling some of the properties of light during the measurement process. Here, the authors show that reflection from a diffusive surface preserves some coherence properties and the shape and the distance to
