Inverse problem of Mueller polarimetry for metrological applications

, 2021
International audienceAbstract Inverse problem of Mueller polarimetry is defined as a determination of geometrical features of the metrological structures (i.e. 1D diffraction gratings) from its experimental Mueller polarimetric signature. This nonlinear

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 ...

Structure‐Response Relationships in Rigid C2‐Symmetric Excitonic Systems: Principles, Modulation, and Functional Design Strategies

ChemPhysChem, Volume 27, Issue 2, January 2026.
Rigid C2‐symmetric chromophores reveal how transition dipole orientation, magnitude, and conformational locking govern exciton coupling and g‐factor amplification, providing a structural blueprint for the rational design of advanced chiroptical molecular and material architectures.

Metasurface-enabled compact, single-shot and complete Mueller matrix imaging

, 2023
When light scatters off an object its polarization, in general, changes - a transformation described by the object's Mueller matrix. Mueller matrix imaging polarimetry is an important technique in science and technology to image the spatially varying ...

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.

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 ...

Diffraction order‐engineered polarization‐dependent silicon nano‐antennas metagrating for compact subtissue Mueller microscopy

Nanophotonics, Volume 14, Issue 27, Page 5277-5289, December 2025.
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.

Classical entanglement in polarization metrology

New Journal of Physics, 2014
Quantum approaches relying on entangled photons have been recently proposed to increase the efficiency of optical measurements. We demonstrate here that, surprisingly, the use of classical light with entangled degrees of freedom can also bring ...

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 ...
