Complex Structured Light Generation Using Printed Liquid Crystal Droplets

Advanced Optical Materials, Volume 13, Issue 33, November 25, 2025.
Inkjet‐printed liquid crystal droplets generate structured light beams with spatially varying polarization and phase. These include full Poincaré beam, vortex beam carrying orbital angular momentum, and beam with polarization singularities, offering a simple approach for compact structured light generation in optical manipulation, imaging, and ...

Thermoplasmonic‐Controlled Optical Filters Based on the Combination of Chiral Liquid Crystals and Metasurfaces

Macromolecular Rapid Communications, Volume 46, Issue 21, November 6, 2025.
A broadband cholesteric liquid crystal (CLC) combined with a bottom‐up metasurface absorber enables the realisation of thermoplasmonic‐controlled optical filters. These filters combine a CLC reflector for visible light with a metasurface absorber operating in the near‐infrared (NIR) range.

Mueller-Polarimetry of Barley Leaves II: Mueller Matrix Decompositions

Photonics
This paper highlights the application of decomposition methods in Mueller polarimetry for the discrimination of three groups of barley leaf samples from Hordeum vulgare: Chlorina mutant, Chlorina etiolated mutant and Cesaer varieties in the visible wavelength at λ = 632.8 nm.

Pseudo‐Dichroism: Nanophotonic Induction of Chiroptical Activity in Symmetric Molecular Systems

Advanced Optical Materials, Volume 13, Issue 24, August 25, 2025.
By analyzing vibrational circular dichroism (VCD) spectra of chiral nanomaterials, we distinguish genuine molecular chirality (true dichroism) from measurement artifacts (pseudo dichroism) using a novel, robust framework. The spectral criteria we establish apply broadly to all chiroptical techniques in nanomaterial research, enhancing precision in ...

Bayesian inference approach for Full Poincaré Mueller polarimetry

Optics & Laser Technology
Full Poincaré Mueller Polarimetry is a new technique for characterizing samples by means of their Mueller matrix. The method is based on the use of a full Poincaré beam as a generator of polarization states. These beams present different polarization states, covering the entire Poincaré sphere surface, at different points in the beam cross section.

Mueller matrix polarimetry of bianisotropic materials [Invited]

Journal of the Optical Society of America B, 2019
Mueller matrix polarimetry is a powerful optical technique for characterization of both anisotropic and bianisotropic materials. This review emphasizes methods for the interpretation of measured Mueller matrices, from the meanings of matrix symmetries, to ab initio calculations of Mueller matrices that begin with Maxwell’s equations operating on ...

Dynamic Mueller matrix polarimetry using generalized measurements

Optics Express
Mueller matrices provide a complete description of a medium’s response to excitation by polarized light, and their characterization is important across a broad range of applications from ellipsometry in material science to polarimetry in biochemistry, medicine and astronomy.
