Martínez Matos, Óscar ; Vaveliuk, Pablo ; Moraes, Fernando Jorge Sampaio ; Fumeron, Sebastien ; Calvo Padilla, María Luisa | Optical Society of America | 2010-06A q-plate is a stratified medium composed of a uniaxial nematic liquid crystal with an inhomogeneous orientation of the optical axis possessing a topological charge q, which looks promising as a switching device. This work reports an approach to[...]texto impreso
Martínez Matos, Óscar ; Torchia, Gustavo Adrián ; Vaveliuk, Pablo ; Bilmes, Gabriel M. ; Tocho, Jorge Omar | IOP Publishing Ltd. | 2002-03Spontaneous noncollinear second harmonic generation in potassium dihydrogen phosphate (KDP) crystals was studied theoretically and experimentally as a function of the scattering centres on the surface of the crystal. A model that explains the ma[...]texto impreso
Vaveliuk, Pablo ; Lencina, Alberto Germán ; Rodrigo Martín-Romo, José Augusto ; Martínez Matos, Óscar | Alan E. Willner, University of Southern California | 2014-04-15In this Letter a new class of light beam arisen from the symmetrization of the spectral cubic phase of an Airy beam is presented. The symmetric Airy beam exhibits peculiar features. It propagates at initial stages with a single central lobe that[...]texto impreso
Monte Muñoz de la Peña, Francisco del ; Martínez Matos, Óscar ; Rodrigo Martín-Romo, José Augusto ; Calvo Padilla, María Luisa ; Cheben, Pavel | Wiley-V C H Verlag Gmbh | 2006-08-04Improved performance of volume holographic sol-gel materials-refractive index modulations in the 10^2 range, diffraction efficiencies near 100 %, and low levels of noise scattering-are reported that arise from the incorporation of Zr-based high [...]texto impreso
Martínez Matos, Óscar ; Calvo Padilla, María Luisa ; Cheben, Pavel ; Delâge, André ; Janz, Siegfried ; Xu, Dan-Xia | Society of Photo-Optical Instrumentation Engineers (SPIE) | 2004We propose a modified arrayed waveguide grating (AWG) demultiplexer formed by an array of parallel ridge waveguides of equal length fabricated in silicon-on-insulator (SOI). Each waveguide contains two sections with different widths. The lenghts[...]
