Optimization of the diffraction efficiency in photorefractive crystals
(Sociedad Española de Optica, 2017-05)
The aim of this work is to study and to optimize the diffraction efficiency in sillenite BTO crystals. A theoretical analysis, where the effects of coupling beams are significant,is carried on. In addition, non-mobile ...
Diffraction efficiency measurement in photorefractive thick volume holograms

Analysis of the diffraction efficiency in transverse configuration in sillenite crystals Bi12TiO20
(Universidad Pedagógica y Tecnológica de Colombia, 2018-06)
Se realiza un estudio teórico en cristales silenitas, donde se obtiene una expresión analítica para la eficiencia de difracción en el régimen de Bragg, en la configuración transversal (K < 001 >). Se considera redes nomóviles ...
Diffraction gratings of isotropic negative-phase velocity materials
(Elsevier Gmbh, 2005-12)
Diffraction of electromagnetic plane waves by the gratings made by periodically corrugating the exposed planar boundaries of homogeneous, isotropic, linear dielectric-magnetic half-spaces is examined. The phase velocity ...
The minimum Euclidean distance principle applied to improve the modulation diffraction efficiency in digitally controlled spatial light modulators
(Optical Society Of America, 2010)
Digital addressing of the electrical signal in spatial light modulators, as it is the case in present liquid crystal on silicon (LCoS) displays, may lead to temporal phase fluctuations in the optical beam. In diffractive ...
Self-stabilized holographic recording in reduced and oxidized lithium niobate crystals
(Elsevier Science BvAmsterdamHolanda, 2004)
Characterization of the anamorphic and spatial frequency dependent phenomenon in liquid crystal on silicon displays
(European Optical Soc, 2011-04)
The diffractive efficiency of Liquid Crystal on Silicon (LCoS) displays can be greatly diminished by the appearance of temporal phase fluctuations in the reflected beam, depolarization effects and also because of phase ...
