Topological Quasiparticles of Light: From Spin‐Orbit Coupling to Photonic Skyrmions

Laser &Photonics Reviews, EarlyView.
This review summarizes recent advances in photonic skyrmions, emphasizing the central role of spin–orbit coupling in their formation. The review discusses how spin–orbit interactions generate skyrmionic textures, examines modulation strategies for their dynamic control, and provides an overview of emerging directions and opportunities where these ...

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

Laser &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.

Metasurfaces in Adaptive Optics: A New Opportunity in Optical Wavefront Sensing

Laser &Photonics Reviews, EarlyView.
Wavefront sensing constitutes a critical component of adaptive optics systems, aimed at quantitatively measuring distorted wavefronts and enabling closed‐loop correction in optical setups. Metasurfaces, as planar optical elements composed of nanoscale structures, provide exceptional freedom in modulating multiple dimensions of the light field.

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

Laser &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.
