A Linear‐to‐Linear Cross‐Polarization Conversion q‐BIC Metasurface for Transmission Mode Mid‐Infrared Spectral Filtering

open access: yesLaser &Photonics Reviews, EarlyView.
Manipulating the ultranarrow linewidth spectral features of quasi bound states in the continuum is challenging. A metasurface supporting linear‐to‐linear cross‐polarization coupling efficiency surpassing 25% is proposed to address the issue. Less than 100 nm linewidth is achieved, enabling the device to be applied to wavelength‐selective polarization ...

Polarized Light Backscattering From Turbid Media: Why Do Rayleigh Scatterers Preserve Linear Polarization More Than Circular Polarization?

open access: yesLaser &Photonics Reviews, EarlyView.
Turbid media containing small‐sized Rayleigh‐regime scatterers present a ‘special case’ in which linearly polarized light is found to be less depolarized than circularly polarized light. The underlying mechanisms that give rise to this phenomenon are not yet understood.

Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials

open access: yesLaser &Photonics Reviews, EarlyView.
This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

Phase‐Retrieved High‐Throughput Multi‐Channel Simultaneous Surface Plasmon Resonance Detection

open access: yesLaser &Photonics Reviews, EarlyView.
This work presents a new phase‐retrieval high‐throughput multi‐channel simultaneous SPR detection framework. By integrating an objective lens‐based coupling system with a rotation‐based ePIE (r‐ePIE) phase retrieval on the back focal planes, this framework significantly reduces the minimum required detection area to reveal localized information.
