Thermodynamic Reversibility in Polarimetry
Photonics, 2022 The action of linear media on incident polarized electromagnetic waves can produce two kinds of thermodynamic irreversible effects, namely, loss of intensity, in general anisotropic, and reduction of the degree of polarization. Even though both phenomena

Polarization Aberration of a Non-Rotationally Symmetric Optical System With Freeform Surfaces
IEEE Access, 2021 Owing to the wide application of freeform surfaces in off-axis optical systems with large apertures, large fields of view, and long focus distances, the polarization effects caused by non-rotationally symmetrical surfaces have a significant impact on the

Reconstructing Three-Dimensional Optical Anisotropy with Tomographic Müller-Polarimetric Microscopy. [PDF]
Adv Sci (Weinh)Tomographic Müller polarimetric microscopy is a novel imaging technique that resolves 3D birefringent properties of bulky samples, unveiling hierarchical nanostructures at microscopic resolution. Based on incoherent visible‐light polarimetry, it achieves experimental simplicity by eliminating phase measurements.

A chiral microchip laser using anisotropic grating mirrors for single mode emission
Nanophotonics, Volume 12, Issue 9, Page 1741-1752, April 2023., 2023 Abstract A pair of nanostructured mirrors made of a diffraction grating inscribed in the top layer of a Bragg mirror are designed such that a phase shift near π and different reflected amplitudes exist between transverse electric (TE) and magnetic (TM) reflected polarization states at normal incidence.

Advanced Optical Materials, Volume 9, Issue 16, August 18, 2021., 2021 Chiral plasmonics fascinates researchers from diverse backgrounds. As the field matures, its transfer toward applications requires easy access to the underlying physics, guidance in proper optical characterization, as well as simple and large‐area methods to fabricate substrates. These issues are addressed with a brief introduction to chiral plasmonics
