Fast Tissue Clearing and Volume Imaging Techniques for Anatomy

open access: yesMicroscopy Research and Technique, EarlyView.
Tissue clearing and volume imaging techniques have revolutionized our ability to visualize large biological samples, but they face obstacles related to speed, tissue preservation, complexity, and the need for fluorescence labels that make them difficult to implement in anatomy and preclinical research.

Orbital Angular Momentum Holography Using Neural Network and Camera in the Loop

open access: yesLaser &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

open access: yesLaser &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.

Nonlinear Distortion Equalization in Multi‐Span Optical Links Via a Feed‐Forward Photonic Neural Network

open access: yesLaser &Photonics Reviews, EarlyView.
A feed‐forward photonic neural network equalizes linear and nonlinear impairments in multi‐span IMDD optical fiber transmission. The linear processing stage employs an 8‐tap optical Finite Impulse Response filter integrated on a silicon photonics platform, while the end‐of‐line photodetector represents the nonlinear stage.
