Orbital Angular Momentum Holography Using Neural Network and Camera in the Loop
Laser &Photonics Reviews, EarlyView.Neural network and optimization‐based approaches are introduced for Orbital Angular Momentum (OAM) multiplexed holography, enabling high‐capacity, phase‐only image reconstruction. A Camera‐In‐The‐Loop (CITL) system learns a realistic propagation model to correct system imperfections.

Diverging Surface Plasmon Polaritons for Single Upconverting Nanoparticle Imaging
Laser &Photonics Reviews, EarlyView.Diverging surface plasmon polaritons (SPPs) are coupled to a gold surface by a grating to excite upconverting nanoparticles (UCNPs) immobilized on the surface. By combining the SPP field enhancement and diverging SPP mode propagation, the detection of individual UCNPs over a large area is possible.
