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
Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Optical Society of America | 2003-03From a theoretical point of view, the use of anisotropic pure-phase plates (APP) is considered in order to improve the quality parameter of certain partially coherent, partially polarized beams. It is shown that, to optimize the beam-quality par[...]texto impreso
The angular momentum of non-uniformly totally polarized beams is investigated using methods from the beam characterization approach. The relationship between the elements of the beam matrix for the two components of the field and the angular mom[...]texto impreso
Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Elsevier Science BV | 2008-02-15In terms of the so-called irradiance moments of a light field, the beam quality change, ?Q, of radially and azimuthally polarized beams caused by propagation through a quartic phase plate (as occurs for example, in strongly pumped laser rods us[...]texto impreso
Piquero Sanz, Gemma María ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Kluwer Academic Publishers | 1995-03The effects that quartic phase distortions generate in tridimensional beam quality parameters of laser fields are investigated. Two cases of special interest are considered: a rationally symmetric spherically aberrated lens, and a pair of identi[...]texto impreso
Piquero Sanz, Gemma María ; Movilla Serrano, Jesús María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Optical Society of America | 1999-11Changes generated by lenslike birefringent elements on the beam-quality parameter of partially polarized beams are investigated. Analytical expressions for the beam-quality gain at the output of such systems are given in terms of the second-orde[...]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 ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | SPIE--The International Society for Optical Engineering | 2006Several overall parameters are introduced to characterize the linear or circular polarization content of a non-uniformly totally polarized beam over the region of its wavefront where the irradiance is significant. These parameters are determined[...]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
Piquero Sanz, Gemma María ; Movilla Serrano, Jesús María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Kluwer Academic Publishers | 1999-03Two overall parameters are proposed to characterize the degree of polarization and its uniformity across the transversal section of non-uniformly partially polarized beams. Such parameters can be measured according to the well-known standard met[...]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[...]
