Assessing Effects of Riboflavin/UV‐A Cross‐Linking on Aqueous Outflow Facility, Corneal Biomechanics and Their Association With Intraocular Pressure

open access: yesJournal of Biophotonics, EarlyView.
Our study demonstrates that UV cross‐linking (CXL) reduces outflow facility while increasing corneal elasticity across IOP levels of 20–40 mmHg, measured using direct manometry and non‐contact optical coherence elastography. These results highlight both parameters as potential indicators for evaluating CXL effectiveness and monitoring keratoconus ...

Extended Learning Robustness for High‐Fidelity Human Face Imaging from Spatiotemporally Decorrelated Speckles

open access: yesLaser &Photonics Reviews, EarlyView.
A GAN‐based framework is proposed that tackles spatiotemporal instabilities of scattering media and addresses decorrelation between training and testing data (no overlap between their collection periods). The trained GAN non‐holographically retrieves high‐fidelity human face images from unstable scattering media and effectively addresses speckle ...

Nearly 180° Field‐of‐View Metalens for Miniaturized Imaging Systems

open access: yesLaser &Photonics Reviews, EarlyView.
A compact, single‐layer metalens is developed with an ultra‐wide field of view of ≈180 degrees. Utilizing a unique quadratic phase profile, this metalens overcomes traditional issues like axial and color dispersion. It operates across red, green, and blue wavelengths with non‐polarized light, promising enhanced imaging capabilities for integration into

Multichannel Detection of Hybrid Spin‐Orbital Mode Pairs

open access: yesLaser &Photonics Reviews, EarlyView.
A multi‐foci metalens is developed to detect hybrid spin‐orbital mode pairs (HSOMPs) in multiple channels. Each light spot can detect a predesigned HSOMP, while the spin states of its components are determined by the arc intensity patterns in the neighboring light spots.

Decoupling Optical and Thermal Dynamics in Dielectric Metasurfaces for Self‐Encoded Photonic Control

open access: yesLaser &Photonics Reviews, EarlyView.
Schematic representation of transmission modulation via photo‐thermo‐optical non‐linearities in a dielectric metasurface. Abstract Thermo‐optical nonlinearities (TONL) in metasurfaces enable dynamic control of optical properties—such as transmitted power, phase, and polarization—through external stimuli like laser irradiation or temperature. Due to the
