Journal ArticleDOI
Modulation of coherence and polarization using liquid crystal spatial light modulators.
Andrey S. Ostrovsky,Gabriel Martínez-Niconoff,Victor Arrizón,P. Martinez-Vara,Miguel A. Olvera-Santamaría,Carolina Rickenstorff-Parrao +5 more
TL;DR: In contrast to a similar technique analyzed by Shirai and Wolf, this method provides a wide range simultaneous modulation of coherence and polarization of electromagnetic fields, employing two crossed zero-twelve nematic liquid crystal spatial light modulators.
Journal ArticleDOI
The van Cittert-Zernike theorem for electromagnetic fields.
TL;DR: The van Cittert-Zernike theorem, well known for the scalar optical fields, is generalized for the case of vector electromagnetic fields and shows that the degree of coherence of the electromagnetic field produced by the completely incoherent vector source increases on propagation whereas thedegree of polarization remains unchanged.
Journal ArticleDOI
Generation of partially coherent diffraction-free fields with tunable geometry.
Gabriel Martínez-Niconoff,Julio C. Ramirez-San-Juan,P. Martinez-Vara,Adrian Carbajal-Dominguez,Andrei S. Ostrovsky +4 more
TL;DR: In this paper, the synthesis of diffraction-free fields with different profiles is described, and the synthesis is done by illuminating a screen containing a circular slit with a cosine beam.
Journal ArticleDOI
Self-focusing transmittances
Gabriel Martínez-Niconoff,J. Munoz-Lopez,J. Silva-Barranco,Adrian Carbajal-Dominguez,P. Martinez-Vara +4 more
TL;DR: The experimental and computational results are in good agreement with the theoretical predictions and show that the changes in the morphology of the diffraction field are bounded by the focusing regions.
Journal ArticleDOI
Surface Plasmon Singularities
Gabriel Martínez-Niconoff,P. Martinez-Vara,G. Diaz-Gonzalez,J. Silva-Barranco,Adrian Carbajal-Dominguez +4 more
TL;DR: In this article, the authors describe the synthesis of optical singularities propagating in the free space and on a metal surface, and show that singularities in free space may generate bifurcation effects while plasmon fields do not generate these kinds of effects.
