Arbitrary polarization control with a segmented APPLE‐II undulator
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.

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

Bayesian inference approach for Full Poincaré Mueller polarimetry [PDF]
© 2023 Elsevier Ltd.Full Poincare 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 Poincare beam as a generator of polarization states.

Visualizing Phase Transition Behavior of Dilute Stimuli Responsive Polymer Solutions via Mueller Matrix Polarimetry [PDF]
Probing volume phase transition behavior of super-diluted polymer solutions both micro- and macroscopically still persist as an outstanding challenge. In this regard, we have explored 4x4 spectral Mueller matrix measurement and its inverse analysis for ...

Probing intrinsic anisotropies of fluorescence: Mueller matrix approach [PDF]
We demonstrate that information on "intrinsic" anisotropies of fluorescence originating from preferential orientation/organization of fluorophore molecules can be probed using a Mueller matrix of fluorescence.

Characterization of photonic structures using visible and infrared polarimetry
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 ...

Complex Structured Light Generation Using Printed Liquid Crystal Droplets
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 ...

Classical entanglement in polarization metrology
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 ...

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.
