Tuning Circular Dichroism and Circularly Polarised Luminescence in Single Crystals of a Perylene Diimide Macrocycle. [PDF]

Angew Chem Int Ed Engl
The circular dichroism (CD) and circularly polarised (CPL) of a bis‐perylene diimide macrocycle are measured in single crystals. These chiroptical properties are tuned by the macrocycle's π–π stacking interactions in the solid‐state. Abstract Chiral materials that manipulate circularly polarised light have burgeoning applications across optoelectronics,

Diffraction order-engineered polarization-dependent silicon nano-antennas metagrating for compact subtissue Mueller microscopy. [PDF]

Nanophotonics
Abstract A polarization‐dependent silicon nano‐antennas metagrating (PSNM) is proposed for parallel polarization transformation by engineering diffraction orders, upon which a compact Mueller microscopy system is implemented for subtissue‐level polarization extraction.

The Combination of Chiral Assembly and Chiral Template Effects Boosts Circularly Polarized Luminescence of Perovskite Nanocrystals

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
We show that the hierarchical order of perovskite nanocrystal assemblies formed within a nanostructured, chal liquid‐crystalline template exhibits extremely high circularly polarized luminescence (CPL). This is due to the helical arrangement of PNCs in the template voids and capitalizes on the inherent electrooptic properties of the template ...

Mueller matrix polarimetry for improved liver fibrosis diagnosis [PDF]

Optics Letters, 2012
An experimental Mueller matrix polarimeter is used to quantify human liver fibrosis by measuring retardance and depolarization of thin biopsies. The former parameter is sensitive to fibrillar collagen, the latter is specifically sensitive to fibrillar collagen around blood vessels, which is not significant for liver fibrosis diagnosis.

Mueller matrix polarimetry using full Poincaré beams

Optics and Lasers in Engineering, 2019
Full Poincaré beams (FPBs) are proposed for polarimetric applications. Such beams present all states of totally polarized light across their transverse section at once and therefore can be considered as parallel polarization state generators. A simple setup, including a FPB as input light, has been designed and implemented to measure the Mueller matrix

Nonclassical Mueller Polarimetry

Optics Express
Quantum correlations are non-classical features of quantum systems that can be harnessed in new technologies. Nonlocality, a unique byproduct of the entanglement of more than one particle, can alter the causal sequence that is present in a classical measurement. In this work, we investigate a nonlocal form of Mueller polarimetry.

Mueller matrix polarimetry with 3D integral imaging

Optics Express, 2019
In this paper, we introduce the Mueller matrix imaging concepts for 3D Integral Imaging Polarimetry. The Mueller matrix of a complex scene is measured and estimated with 3D integral imaging. This information can be used to analyze the complex polarimetric behavior of any 3D scene.

Engineering Chiroptical Interactions through Integrating Plasmonic Arrays with Cholesteric Nanocellulose

Advanced Materials, Volume 38, Issue 16, 17 March 2026.
In this study, we demonstrate how the combination of plant‐based cellulose and gold nanoparticle lines produces robust, tunable chiral light control in composite films. The resulting plasmonic cellulose composite exhibits a strong plasmonic CD at the surface lattice resonance, along with an inversion of chiroptical response upon reversing the ...

Preservation of Historically and Scientifically Important Geospatial Data From Venus

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract A large volume of scientifically and historically important data from the early exploration of Venus is not widely available to researchers. Our work is focused on ameliorating this problem with the archival of geospatial data including radar, topography, and radiometry.

Polarized Light Backscattering From Turbid Media: Why Do Rayleigh Scatterers Preserve Linear Polarization More Than Circular Polarization?

Laser &Photonics Reviews, Volume 20, Issue 4, 19 February 2026.
Turbid media containing small‐sized Rayleigh‐regime scatterers present a ‘special case’ in which linearly polarized light is found to be less depolarized than circularly polarized light. The underlying mechanisms that give rise to this phenomenon are not yet understood.
