On a heuristic point of view concerning the optical activity
Chun-Fang Li, Zhi-Juan Hu
Motivated by a recent finding that Fresnel's phenomenological description of the optical activity in the chiral medium is not self-consistent, we conduct a thorough investigation i…
No circular birefringence in a chiral medium: an analysis of single-mode refraction
Zhi-Juan Hu, Chun-Fang Li
It is generally believed that the right-handed circularly polarized (RCP) and left-handed circularly polarized (LCP) waves in an isotropic chiral medium propagate at different velo…
From Poynting vector to new degree of freedom of polarization
Xiao-Lu You, Chun-Fang Li
Up till now, the Jones vector is, strictly speaking, only a notion about the state of polarization of plane electromagnetic waves though it is generally applied to paraxial fields…
New mechanism for polarization singularity of vector vortex beams
Chun-Fang Li
It was recently realized that the polarization bases of the plane-wave modes in the integral representation of a light beam need to be determined by a degree of freedom arising fro…
Are vector vortex beams endowed with any entanglement?
Chun-Fang Li
Polarization of light beams is one of the most important physical phenomena. But up till now it was only described in the paraxial approximation in which it is considered to be a s…
A full characterization of the polarization of vector light beams
Chun-Fang Li
We present an approach to fully characterize the polarization of general vector light beams. When attempting to generalize the notion of Stokes parameters to nonparaxial light beam…
