Affine diffractive beam dividers
F. Gori, R. Martinez-Herrero, O. Korotkova +5
Diffractive optical elements that divide an input beam into a set of replicas are used in many optical applications ranging from image processing to communications. Their design re…
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 z-coherence of beams radiated by Schell-model sources with Gaussian profile
M. Santarsiero, G. Piquero, J. C. González de Sande +3
The degree of coherence and the intensity distribution on the axis of the beam radiated by a planar partially coherent source of the Schell-model type are investigated. We present…
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…
Three-dimensional polarization of fields radiated by partially coherent electromagnetic cylindrical sources
M. Santarsiero, J. C. G. De Sande, O. Korotkova +3
Partially coherent electromagnetic sources with cylindrical symmetry and infinite extent radiating outwards are introduced. Their cross-spectral density matrix is given…
