Journal ArticleDOI
Generation of the "perfect" optical vortex using a liquid-crystal spatial light modulator
TL;DR: It is shown analytically and experimentally that such a vortex can be approximately generated in the Fourier transforming optical system with a computer-controlled liquid-crystal spatial light modulator.
Journal ArticleDOI
Simple technique for generating the perfect optical vortex
Joaquín García-García,Carolina Rickenstorff-Parrao,Ruben Ramos-Garcia,Victor Arrizón,Andrey S. Ostrovsky +4 more
TL;DR: An improved technique for generating the perfect optical vortex is proposed and is notable for the simplicity of its practical realization and high quality of the results.
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
Experimental generating the partially coherent and partially polarized electromagnetic source.
Andrey S. Ostrovsky,Gustavo Rodriguez-Zurita,Cruz Meneses-Fabian,Miguel A. Olvera-Santamaría,Carolina Rickenstorff-Parrao +4 more
TL;DR: The technique for generating the partially coherent and partially polarized source starting from the completely coherent and completely polarized laser source is proposed and analyzed and the efficiency of this technique is illustrated.
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.
