Design and characterization of a simple polarization grating-based polarimeter
Massimo Santarsiero, J. C. G. de Sande, Gemma Piquero
In undergraduate optics courses, diffraction gratings are studied extensively, generally within the scalar approximation. When the vector nature of light is taken into account, so-…
On z-coherence in self-focusing
F. Gori, R. MartÃnez-Herrero, G. Piquero +3
Both the intensity distribution and the degree of coherence between pairs of points along the propagation axis (z-coherence) are derived in closed form for a phenomenon of self-foc…
On-axis polarization of beams radiated by electromagnetic circularly coherent sources
J. C. Gonzalez de Sande, O. Korotkova, M. Santarsiero +3
Partially coherent electromagnetic sources with cylindrical symmetry and infinite extent radiating outwards are introduced. Their 3x3 cross-spectral density matrix is given through…
Tailoring on-axis spectral density with circularly coherent light beams
O. Korotkova, J. C. de Sande, M. Santarsiero +3
The on-axis cross-spectral density (CSD) of a beam radiated by a stationary source with a circular coherence state and a Gaussian spectral density is obtained in the closed form. I…
