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
We present a theoretical framework for the study of surface-plasmon polariton (SPP) packets propagating along a lossy metal-dielectric interface within the paraxial approximation. Using a rigorous formulation based on the plane-wave spectrum for[...]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
Serna Galán, Julio ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Taylor and Francis Ltd. | 1992-03The quality behaviour of Gaussian Schell-model fields propagating through general (non-orthogonal) ABCD optical systems has been characterized by introducing a number of parameters. Such parameters have been given in terms of the Wigner distribu[...]texto impreso
Serna Galán, Julio ; Martínez Herrero, Rosario ; Mejías Arias, Pedro Miguel | Chapman & Hall Ltd. | 1992-09An analytic and measurable beam parameter is defined for beams emerging from heterojunction monomode diode lasers with very thin active layers, which provides a joint description of their focusing capabilities and far field divergence behaviour.[...]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.

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
Martínez Herrero, Rosario ; Maluenda, David ; Juvells, Ignasi ; Carnicer, Artur | IEEE Computer Society | 2019-02-18According to intensity consideration along the propagation axis, we derived mathematical conditions for a family of modulating functions able to produce needles of arbitrary length, sub-wavelength width and almost constant irradiance. These func[...]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.

Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Gustav Fischer Verlag | 1997-03The behaviour of thin pure phase transmittances is represented by means of a generalized matrix, M, which can be handled as the ABCD-matrices associated with ordinary first-order optical systems. This formalism enables the application of general[...]texto impreso
