Reciprocal Asymmetric Transmission in Directionally Metallized Silica Nanogratings With Broken Lateral Mirror Symmetry

open access: yesNanophotonics, Volume 15, Issue 15, 13 August 2026.
Directional silver coating breaks lateral mirror symmetry in a reciprocal silica nanograting. Opposite in‐plane illumination directions redistribute optical power differently among diffraction and absorption channels, producing strong polarization‐preserving lateral transmission contrast.

Full‐Stokes Polarimetry Metasurface‐Enabled Single‐Shot Measurement of the Spin Hall Effect of Light

open access: yesAdvanced Optical Materials, Volume 14, Issue 30, 14 August 2026.
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.

HYBRID COMPRESSION OF CERVICAL IMAGES BY SEGMENTING NUCLEI-CYTOPLASM [PDF]

open access: yesICTACT Journal on Image and Video Processing, 2012
A hybrid image compression method is proposed by which the Nuclei-Cytoplasm of the image is completely restorable and the background part of the image is restorable with insignificant loss.

Stokes‐Based 3D Polarimetric Analysis of Dipolar Near‐Fields

open access: yesAdvanced Photonics Research, Volume 7, Issue 8, August 2026.
Characterizing the near‐field polarization of dipolar emitters is of growing importance in nanophotonics, since many subwavelength systems resemble their emission. In this work, we apply the 3D Stokes formalism and its intrinsic reference frame to analyze the polarization properties of various dipole emitters from the near‐ to the far‐field, allowing a

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

open access: yesLaser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Sample-Based Gradient Edge and Angular Prediction for VVC Lossless Intra-Coding

open access: yesApplied Sciences
Lossless coding is a compression method in the Versatile Video Coding (VVC) standard, which can compress video without distortion. Lossless coding has great application prospects in fields with high requirements for video quality.
