Arbitrary polarization control with a segmented APPLE‐II undulator

Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 73-83, January 2026.
A four‐segmented APPLE‐II undulator was constructed, and its operation has started at NanoTerasu BL13U. The performance of arbitrary polarization control using phase shifters is demonstrated.A newly developed four‐segmented APPLE‐II undulator enables arbitrary polarization control in the soft to tender X‐ray region.

Complete Mueller matrix from a partial polarimetry experiment: the nine-element case

, 2019
International audienceWe show that an incomplete, nine-element Mueller matrix with a row and a column missing, obtained in a partial polarimetry experiment, can be completed to a full, 16-element Mueller matrix, provided depolarization is absent ...

Compound meta‐optics: there is plenty of room at the top

Nanophotonics, Volume 14, Issue 23, Page 3835-3849, 02 November 2025.
Abstract Metasurfaces have been widely exploited in imaging and sensing, holography, light–matter interaction, and optical communications in free space and on chip, thanks to their CMOS compatibility, versatility and compact form. However, as this technology matured from novelty to performance, stringent requirements on diffraction efficiency ...

From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies

Advanced Functional Materials, Volume 35, Issue 45, November 5, 2025.
This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.

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.

Characterization of photonic structures using visible and infrared polarimetry

EPJ Web of Conferences, 2010
Photonic Crystals are materials with a spatial periodic variation of the refractive index on the wavelength scale. This confers these materials interesting photonic properties such as the existence of photonic bands and forbidden photon frequency ...

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 ...
