Martínez Herrero, Rosario ; Piquero Sanz, Gemma María ; González de Sande, Juan Carlos ; Santarsiero, Massimo ; Gori, Franco | MDPI | 2019-07-01Partially coherent sources with non-conventional coherence properties present unusual behaviors during propagation, which have potential application in fields like optical trapping and microscopy. Recently, partially coherent sources exhibiting [...]texto impreso
Piquero Sanz, Gemma María ; Santarsiero, Massimo ; Gori, Franco ; González de Sande, Juan Carlos | IOP Publishing, Ltd. | 2013-05Planar electromagnetic sources characterized by a periodic variation of their beam coherence-polarization matrix are investigated, as far as the polarization features of the radiated fields are concerned, within the framework of the paraxial app[...]texto impreso
Piquero Sanz, Gemma María ; Gori, Franco ; Santarsiero, Massimo ; Simon, Raja ; Borghi, Riccardo ; Guattari, Giorgio | Optical Society of America | 2003-01It is shown that any partially polarized, partially coherent source can be expressed in terms of a suitable superposition of transverse coherent modes with orthogonal polarization states. Such modes are determined through the solution of a syste[...]texto impreso
González de Sande, Juan Carlos ; Santarsiero, Massimo ; Gori, Franco ; Piquero Sanz, Gemma María | Optical Society of America | 2014-04-01Generally speaking, the difference between two cross-spectral densities (CSDs) does not represent a correlation function. We will furnish a sufficient condition so that such difference be a valid CSD. Using such a condition, we will show through[...]texto impreso
Piquero Sanz, Gemma María ; Santarsiero, Massimo ; González de Sande , Juan Carlos ; Gori, Franco | The Optical Society Of America | 2012-12-03The polarization characteristics of unpolarized light passing through a double wedge depolarizer are studied. It is found that the degree of polarization of the radiation propagating after the depolarizer is uniform across transverse planes afte[...]texto impreso
Piquero Sanz, Gemma María ; González de Sande, Juan Carlos ; Santarsiero, Massimo ; Gori, Franco | IOP Publishing, Ltd. | 2014-03The irradiance and polarization characteristics of quasi-monochromatic partially coherent electromagnetic beams are analyzed when they propagate after passing through a deterministic linear optical element, i.e., an optical element that can be r[...]texto impreso
Piquero Sanz, Gemma María ; Santarsiero, Massimo ; Gori, Franco ; Borghi, Riccardo | IOP Publishing Ltd. | 2001-01We consider a class of beams that are both partially polarized and partially coherent from the spatial standpoint. They are characterized by a correlation matrix whose elements have the same form as the mutual intensity of a Gaussian Schell-mode[...]texto impreso
Martínez Herrero, Rosario ; Maluenda, David ; Piquero Sanz, Gemma María ; González de Sande, Juan Carlos ; Santarsiero, Massimo ; Gori, Franco | Spie-Int Soc Optical Engineering | 2017In this work a new type of partially polarized and partially coherent sources is proposed. The coherence characteristics of these sources are dependent on the difference of the radial distances from the source center of the two points to be comp[...]texto impreso
Sande, J.C,G. de ; Martínez Herrero, Rosario ; Piquero Sanz, Gemma María ; Santarsiero, Massimo ; Gori, Franco | Optical Society of America | 2019-02-18Partially coherent pseudo-Schell model sources are introduced and analyzed. They present radial symmetry and coherence characteristics depending on the difference between the radial distances of two points from the source center. As a consequenc[...]texto impreso
Piquero Sanz, Gemma María ; Gori, Franco ; Romanini, P. ; Santarsiero, Massimo ; Borghi, Riccardo ; Mondello, A. | Elsevier Science BV | 2002-07-01An experimental procedure for the synthesis of a class of partially polarized Gaussian Schell-model sources is proposed. The experimental set-up is based on Mach-Zenhder interferometer. This kind of sources give rise to not only a coherence degr[...]texto impreso
González de Sande, Juan Carlos ; Santarsiero, Massimo ; Piquero Sanz, Gemma María ; Gori, Franco | IOP Publishing | 2015-12Using recently derived results about the difference of two cross-spectral densities, we consider a source whose correlation function is the difference of two mutually displaced Gaussian Schell-model cross-spectral densities. We examine the main [...]texto impreso
Piquero Sanz, Gemma María ; Borghi, Riccardo ; Gori, Franco ; Santarsiero, Massimo | The Optical Society Of America | 2000-09-01We introduce an extension of the van Cittert-Zernike theorem to spatially incoherent sources with partial polarization. We show through a simple example that fields generated by such sources can possess correlation matrices with interesting prop[...]
