Summary: The dynamic viscoelasticity and dynamic birefringence of a microgel system were investigated to clarify the molecular origin of the viscoelastic response. Different behaviors were observed at concentrations below and above a critical value for random close packing, with multiple relaxation mechanisms involved in the liquid-like regime and a single dominant stress origin in the solid-like regime. The measurements were qualitatively supported by the Onuki-Doi theory.

Summary: Variations in viewing angle of a metallic U-shaped nanoantenna can lead to different size and shape projections. Plasmonic metasurfaces consisting of arrays of such nanoantennas show unique side scattering switching and routing processes, including polarization switching centered at 1.6 μm and spectrally broadband directional control of in-plane light scattering. The results also highlight the impact of surface lattice resonance on infrared scattering and its switching process.

Summary: Polarization-sensitive optical coherence tomography (PS-OCT) is a functional extension of standard OCT, which can be categorized into multi-input polarization state (multi-IPS) and single IPS systems. However, calibrating the polarization states for fiber-based systems and achieving compactness and robustness for bulk optics-based systems are challenging.

Summary: Nanocelluloses are promising materials for creating structured films with unique optical properties through different preparation techniques. This study investigated the fabrication of birefringent and chiral films from non-sonicated CNC suspensions using a shear-coating method, showing the evolution of suspensions from a gel-like shear-thinning fluid to isotropic and chiral nematic liquid crystalline phases. The films prepared from non-sonicated fresh CNC suspensions exhibit birefringence, while those from stored suspensions reflect left-handed polarized light, with quantification achieved using a Mueller matrix formalism.

Summary: The polarization analysis of thin SiO2 films deposited on resist pillar arrays was conducted using synchrotron-based FTIR microspectroscopy. It was found that the changes in absorption band intensity followed the angular dependence of cos(2)theta, indicating absorption anisotropy. The study also identified the strongest absorption peak at 1040 +/- 20 cm(-1), which has potential applications in sensor technology and radiative cooling.

Summary: The relative error of a fiber optic current sensor (FOCS) increases quadratically with the electric current to be measured, mainly due to the residual linear birefringence of the spun fiber used in the FOCS. However, by measuring the residual linear birefringence and circular birefringence of the spun fiber, the FOCS' relative error can be significantly reduced, improving its accuracy.

Summary: This study introduces a spectroscopic Mueller matrix ellipsometer based on two rotating Fresnel rhomb compensators with nearly achromatic response and optimal retardance. The instrument allows for well-conditioned measurement even for low intensity samples due to the compensators rotating in a discrete manner instead of continuously rotating. An optimization algorithm determines the optimal set of discrete angles to determine the Mueller matrix in the presence of noise, and experimental Mueller matrices are provided as examples.

Summary: In this letter, a new design for elliptical retarders based on two quarter-wave retarders with an angle offset is presented, which is suitable for polarimetric measurements based on rotating compensator systems. This design offers the minimum condition number achieved by traditionally optimal polarimeter setups, and can further improve the accuracy of polarimetric imaging measurements in the presence of error sources, with the advantage that it only requires common quarter-wave retarders.

Summary: A complete formulation of the electromagnetic problem for light incidence from a transparent to an absorbing medium (isotropic materials) is presented. All relevant formulas that relate the polarization and Poynting vectors of the reflected and transmitted beams to the incident ones are explicitly obtained based on the standard separation in s and p polarization cases. The procedure is overall compact, being both concise and comprehensive.

Summary: This study presents a new approach using Mueller matrix polarimetry to investigate symmetry-breaking processes during crystallization. By applying this method to cooling NaClO3 solutions, the researchers demonstrate its capability to capture the entire process, including the initial and final stages as well as the intermediate steps and dynamics. This technique provides more comprehensive information and insights into the symmetry-breaking mechanisms involved in crystal formation. Overall, this study highlights the potential of Mueller matrix polarimetry for in situ statistical measurements of optical rotation and monitoring the evolution of enantiomeric excesses.

Summary: This work expands the use of spectroscopic ellipsometry to surfaces with roughness that is similar to or larger than the wavelength of the incident light. By using a custom-built spectroscopic ellipsometer and varying the angle of incidence, we were able to differentiate between the diffusely scattered and specularly reflected components. Our findings demonstrate that measuring the diffuse component at specular angles is highly beneficial for ellipsometry analysis, as its response is equivalent to that of a smooth material. This allows for accurate determination of the optical constants in materials with extremely rough surfaces. Our results have the potential to broaden the scope and utility of the spectroscopic ellipsometry technique.

Summary: This Letter demonstrates the benefits of using a complete temporal basis in polarimeters based on photoelastic modulators rather than the commonly used truncated temporal basis. The truncated basis leads to a discrete selection of Fourier harmonics for data processing. The results are numerically and experimentally illustrated for a complete Mueller-matrix-based polarimeter on four photoelastic modulators.

Summary: This study investigates the polarimetric properties of skin, skeletal muscle, connective tissue, and fat using Mueller matrix imaging. It compares their characteristics and how they change with wavelength, including during meat aging. In-vivo and ex-vivo experiments reveal wavelength-driven tissue property variations, notably significant in depolarization effects. Differences in polarimetric traits exist, with skeletal muscle's reduced retardation and fat's increased retardation over 24 h being significant findings.

Summary: Spontaneous chiral symmetry breaking is a phenomena observed in various systems, but its origin is still debated. The energy difference between intermediate states of optical enantiomers has been suggested to be the cause of symmetry breaking, but the reason behind this is unclear. By measuring the optical rotation angle of NaClO3 enantiomeric crystals during their formation, it has been found that the energy needed to induce enantiomeric excess is equal to the energy dissipated from the solid salt, supporting the proposed model of entropy production. This understanding of chiral symmetry breaking can help explain the formation of self-organised structures and have implications for advanced materials and synthetic biological tissues.

Summary: Optically anisotropic materials form through colloidal lithography were studied using SEM, confocal microscopy, and polarimetry. A hexagonal array mask made of sub-micron silica particles was created via Langmuir-Blodgett self-assembly, and the pattern was transferred onto silicon and glass substrates using ion beam etching. Gold films were then deposited onto the etched pillars to enhance optical properties. Polarimetric measurements showed that the etching directions influenced the linear birefringence and linear dichroism, with the chiroptical responses increasing with the angle of incidence.
