Depth aberrations characterization in linear and nonlinear microscopy schemes using a Shack-Hartmann wavefront sensor
Aviles Espinosa, Rodrigo; Andilla, Jordi; Porcar-Guezenec, Rafael; Levecq, Xavier; Artigas García, David; Loza Álvarez, Pablo (2012)
Text en actes de congrés
Accés restringit per política de l'editorialThe performance of imaging devices such as linear and nonlinear microscopes (NLM) can be limited by the optical properties of the imaged sample. Such an important aspect has already been described using theoretical models ... -
Dispersion-managed cnoidal pulse trains
Kartashov, Yaroslav V.; Vysloukh, Victor A.; Marti-Panameño, E.; Artigas García, David; Torner Sabata, Lluís (2003-08)
Article
Accés restringit per política de l'editorialWe report on the existence and properties of breathing periodic cnoidal pulse trains propagating in dispersion managed systems with piecewise constant dispersion. Our numerical investigations show that the dispersion ... -
Dyakonov surface wave resonant transmission
Takayama, Osamu; Nikitin, A. Yu; Martin-Moreno, Luis; Torner Sabata, Lluís; Artigas García, David (2011-03-28)
Article
Accés restringit per política de l'editorialThe role of Dyakonov surface waves in the transmission through structures composed of birefringent media is theoretically explored. In the case of structures using prisms, unexpected high transmission above the critical ... -
Dyakonov surface waves

Dyakonov surface waves in photonic metamaterials
Artigas García, David; Torner Sabata, Lluís (2005-01)
Article
Accés restringit per política de l'editorialWe show that suitable photonic metamaterial structures can support lossless surface waves of the form envisaged by Dyakonov. The idea we put forward is based on the birefringent properties of photonic crystals in the ... -
Dynamic behaviour in a nonlinear directional coupler with feedback
Artigas García, David; Dios Otín, Víctor Federico; Canal Bienzobas, Fernando (TAYLOR & FRANCIS LTD, 1997-06-30)
Article
Accés obertA new kind of resonator based on a nonlinear directional coupler with feedback is presented. The steady states are found and the map of the system is iterated, showing the existence of bistability, period doubling and ... -
Dynamics of quadratic soliton excitation
Artigas García, David; Torner Sabata, Lluís; Akhmediev, N (1999-04)
Article
Accés restringit per política de l'editorialWe study the dynamics of the soliton–radiation interaction in the process of soliton excitation in quadratic nonlinear media. The focus is on the dynamics of initial signals that are not weakly perturbed exact solitons. ... -
Effect of molecular organization on the image histograms of polarization SHG microscopy
Psilodimitrakopoulos, Sotiris; Amat Roldán, Iván; Loza Álvarez, Pablo; Artigas García, David (2012)
Article
Accés obertBased on its polarization dependency, second harmonic generation (PSHG) microscopy has been proven capable to structurally characterize molecular architectures in different biological samples. By exploiting this polarization ... -
Efficiency of quadratic soliton generation
López Lago, Elena; Simos, Christos; Couderc, Vincent; Barthélémy, Alain; Artigas García, David; Torner Sabata, Lluís (2001-08)
Article
Accés restringit per política de l'editorialWe report what is believed to be the first experimental demonstration of soliton content as a function of the intensity of input light for multicolor quadratic solitons. Experiments were conducted with spatial solitons ... -
Enhanced localization of Dyakonov-like surface waves in left-handed materials
Crasovan, L C; Takayama, Osamu; Artigas García, David; Johansen, S K; Mihalache, Dumitru; Torner Sabata, Lluís (2006-10)
Article
Accés restringit per política de l'editorialWe address the existence and properties of hybrid surface waves forming at interfaces between left-handed materials and dielectric birefringent media. The existence conditions of such waves are found to be highly relaxed ... -
Estimating the helical pitch angle of amylopectin in starch using polarization second harmonic generation microscopy
Psilodimitrakopoulos, Sotiris; Amat Roldán, Iván; Loza Álvarez, Pablo; Artigas García, David (2010-08)
Article
Accés restringit per política de l'editorialStarch granules are among the brightest natural second harmonic generation (SHG) converters. They basically consist of amylose and amylopectin molecules and the source of the SHG signal is still undetermined. In the ... -
