Suárez Bermejo, J. C. ; González de Sande, Juan Carlos ; Santarsiero, Massimo ; Piquero Sanz, Gemma María | IEEE | 2019The main error sources of a recently proposed Mueller matrix polarimetric method based on the use of full Poincare beams (FPBs) are described and analysed in detail. Numerical simulations are performed under the presence of different sources of [...]texto impreso
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 ; Borghi, Riccardo ; Mondello, A. ; Santarsiero, Massimo | Elsevier Science BV | 2001-08-15We analyze the polarization features of the beam, generated by a class of partially polarized quasi-homogeneous sources, which propagates through a polarization grating. Analytical expressions in the far zone for the beam coherence polarization [...]texto impreso
González de Sande, Juan Carlos ; Santarsiero, Massimo ; Piquero Sanz, Gemma María | Spie-Int Soc Optical Engineering | 2017The generation of non-uniformly totally polarized beams and the study of their applications is a subject of increasing interest in the last years. A particular class of beams of this kind are the so-called full Poincare beams, which have the pro[...]texto impreso
Piquero Sanz, Gemma María ; Borghi, Riccardo ; Santarsiero, Massimo | Optical Society of America | 2001-06The effects of polarization gratings on partially coherent beams are investigated by studying a Gaussian Schell-model beam impinging on a linear polarizer whose transmission axis varies periodically along one transverse direction. Analytical exp[...]texto impreso
Piquero Sanz, Gemma María ; Ramírez Sánchez, Victoria ; Santarsiero, Massimo | IOP Publishing Ltd. | 2009-08Recently introduced global parameters for describing the polarization of a beam are used to characterize spirally polarized fields, which include as particular cases azimuthally and radially polarized fields. Theoretical predictions about such g[...]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
González de Sande, Juan Carlos ; Piquero Sanz, Gemma María ; Santarsiero, Massimo | Scitepress | 2017A simple method for Mueller matrix polarimetry is proposed. The experimental set up is based on using an azimuthally polarized input beam, which presents all possible linearly polarized states across its transverse section, and an adapted commer[...]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
Santarsiero, Massimo ; Martínez Herrero, Rosario ; Maluenda, David ; González de Sande, J.C. ; Piquero Sanz, Gemma María ; Gori, F. | Optical Soc Amer | 2017-04-15A new class of partially coherent light sources is introduced. At the source plane, they exhibit perfect coherence along any annulus that is concentric to the source center. Between two points at different distances from the center, coherence ca[...]texto impreso
Piquero Sanz, Gemma María ; Santarsiero, Massimo ; Martínez-Herrero, M. ; González de Sande, Juan Carlos ; Alonzo, M. ; Gori, F. | Optical Society of America | 2018-05-15Partially coherent sources with radial coherence are proposed. They present a circularly symmetric intensity profile and a degree of coherence whose absolute value only depends on the angular difference between the two considered points. In part[...]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[...]
