Mueller Matrix Polarimetry on Cyanine Dye J-Aggregates
Molecules, 2023 Cyanine dyes are known to form H- and J-aggregates in aqueous solutions. Here we show that the cyanine dye, S0271, assembles in water into vortex induced chiral J-aggregates. The chirality of the J-aggregates depends on the directionality of the vortex. This study utilised both conventional benchtop CD spectropolarimeters and Mueller matrix polarimetry.

Synthetic Mueller imaging polarimetry
Photonics, 2023 The transformation of the state of polarization of a light beam by its linear interaction with a material medium can be modeled through the Stokes-Mueller formalism. The Mueller matrix associated with a given interaction depends on many aspects of the measurement configuration.

Nonlinear Stokes-Mueller polarimetry [PDF]
Physical Review A, 2016 The Stokes Mueller polarimetry is generalized to include nonlinear optical processes such as second- and third-harmonic generation, sum- and difference-frequency generations. The overall algebraic form of the polarimetry is preserved, where the incoming and outgoing radiations are represented by column vectors and the intervening medium is represented ...

Mueller Matrix Polarimetry with Invariant Polarization Pattern Beams [PDF]
Photonics, 2021 A wide class of nonuniformly totally polarized beams that preserve their transverse polarization pattern during paraxial propagation was studied. Beams of this type are of interest, in particular, in polarimetric techniques that use a single input beam for the determination of the Mueller matrix of a homogeneous sample.

Full Poincaré Mueller Polarimetry Using a CCD Camera
Photonics, 2022 A new method is proposed to perform Mueller matrix polarimetry using a Full Poincaré beam (i.e., a non-uniformly polarized beam presenting all polarization states across its section) as a parallel polarization state generator and a charge-coupled device (CCD) camera as a detector of the polarization state analyzer.

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.The circular dichroism (CD) and circularly polarised (CPL) of a bis‐perylene diimide macrocycle are measured in single crystals. These chiroptical properties are tuned by the macrocycle's π–π stacking interactions in the solid‐state. Abstract Chiral materials that manipulate circularly polarised light have burgeoning applications across optoelectronics,

A multiscale Mueller polarimetry module for a stereo zoom microscope [PDF]
Biomedical Engineering Letters, 2019 Mueller polarimetry is a quantitative polarized light imaging modality that is capable of label-free visualization of tissue pathology, does not require extensive sample preparation, and is suitable for wide-field tissue analysis. It holds promise for selected applications in biomedicine, but polarimetry systems are often constrained by limited end ...

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.We show that the hierarchical order of perovskite nanocrystal assemblies formed within a nanostructured, chal liquid‐crystalline template exhibits extremely high circularly polarized luminescence (CPL). This is due to the helical arrangement of PNCs in the template voids and capitalizes on the inherent electrooptic properties of the template ...
