Training to meet the need for refractive error services
Community Eye Health Journal, 2007 In many low- and middle-income countries, there are inadequate refractive error services for the many people who are currently either blind or visually impaired because they lack a pair of spectacles.The prioritisation of refractive error and low vision ...

Microcone Array‐Mediated Distance Tuning for Photonic Nanojet‐Amplified SERS
Advanced Optical Materials, EarlyView.A tunable microcone array platform provides precise vertical gap control between dielectric microspheres and a SERS‐active surface. This structural regulation aligns the photonic nanojet focal point with plasmonic hotspots, delivering a 15‐fold optical signal enhancement.

Full‐Stokes Polarimetry Metasurface‐Enabled Single‐Shot Measurement of the Spin Hall Effect of Light
Advanced Optical Materials, EarlyView.This study presents a metasurface‐enabled approach to measure the spin Hall effect of light in a single‐shot. The metasurface splits a reflected light into six polarization‐dependent focal spots, allowing all Stokes parameters to be obtained from single image.

Strong Coupling in all‐Polymer Planar Microcavities
Advanced Optical Materials, EarlyView.Strong Coupling has been achieved in an all‐polymer microcavity with dielectric contrast Δn = 0.33 doped with TDBC. A Rabi splitting of 39 meV has been measured opening novel perspectives for polymer photonics. ABSTRACT In this work, strong coupling effect is observed in all‐polymer planar microcavities incorporating TDBC J‐aggregates dispersed into ...

Advanced Optical Materials, EarlyView.Germanium (Ge) all‐dielectric metasurfaces can be leveraged to strongly enhance the radiative emission from Ge layers grown on silicon‐on‐insulator substrates by industry‐standard processes. At room‐temperature, the narrowband photoluminescence (PL) intensity is enhanced by a factor ∼40× with respect to unstructured films.

Advanced Photonics Research, Volume 6, Issue 5, May 2025.Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...
