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 ; 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
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 ; 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
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
Piquero Sanz, Gemma María ; Borghi, Riccardo ; Santarsiero, Massimo | Elsevier Science BV | 2001-07-15From a recently proposed technique, used to determine the modal weights of beams made up of incoherent superpositions of Hermite-Gaussian (PIG) modes, we derive the analytical expression of a family of functions which are biorthogonal to the squ[...]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[...]
