Seminar: “Correlation between Parameters of Optical Field
Angular Momentum in the Vicinity of Optical Singularity" by Prof. Igor

Abstract:
The relations between distributions associated with
different optical parameters are considered. Such kinds of relations are
analyzed: intensity – polarization; intensity – azimuth of transversal Poynting
vector component; azimuth of transversal Poynting vector component – modulus of
this component; azimuth of transversal Poynting vector component –
polarization. It is shown that such relations may be realized as correlation or
“anticorrelation”. For example, intensity of field has small gradient in areas
where the polarization changes quickly. The method of measurement of
characteristics of Poynting vector components is proposed. The results of
experimental confirmation are presented. The angular momentum in the area of
C-point (point of circular polarization) is considered. It is shown that spin
angular momentum of quasi-chromatic “simple” beam like Gaussian practically
does not depend on time coherency. The results of experimental investigations
are presented.
