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

Existence loci of bound states in the continuum in the parameter space of anisotropic planar structures
Mukherjee, Samyobrata; Gomis Bresco, Jordi; Pujol Closa, Maria del Pilar; Artigas García, David; Torner Sabata, Lluís (Optical Society of American (OSA), 2019)
Comunicació de congrés
Accés obertBound states in the continuum (BICs), first predicted in the field of quantum physics [1], are localized radiationless states existing in the part of the spectrum that corresponds to radiative modes. BICs are a general ... -
Fast monitoring of in-vivo conformational changes in myosin using single scan polarization- SHG microscopy
Psilodimitrakopoulos, Sotiris; Loza Álvarez, Pablo; Artigas García, David (2014-12-01)
Article
Accés restringit per política de l'editorialFast imaging of molecular changes under high-resolution and label-free conditions are essential for understanding in-vivo processes, however, current techniques are not able to monitor such changes in real time. Polarization ... -
Generation of multicolor spatial solitons with pulsed light
Carrasco Rodríguez, Sílvia; Pérez Torres, Juan; Artigas García, David; Torner Sabata, Lluís (2001-05)
Article
Accés restringit per política de l'editorialThe impact of temporal effects to the generation of multiple wave quadratic spatial solitons with pulsed light is shown. We examine soliton formation under conditions of second-harmonic generation but our conclusions are ... -
Imaging amylopectin's order in starch using 3-dimensional polarization SHG
Psilodimitrakopoulos, Sotiris; Amat Roldán, Iván; Artigas García, David; Loza Álvarez, Pablo (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2011)
Text en actes de congrés
Accés restringit per política de l'editorialIn minimally destructive SHG biomedical imaging (high resolution optical slicing) is greatly desirable to extract the maximum of information from the light matter interaction. Here we develop a 3-D biophysical model and ... -

Lossless directional guiding of light in dielectric nanosheets using Dyakonov surface waves
Takayama, Osamu; Artigas García, David; Torner Sabata, Lluís (2014-06-01)
Article
Accés restringit per política de l'editorialGuiding light at the nanoscale is usually accomplished using surface plasmons(1-12). However, plasmons propagating at the surface of a metal sustain propagation losses. A different type of surface excitation is the Dyakonov ... -
