Turbulence control by non-Hermitian potentials
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessWe propose a method to control turbulence by the introduction a non-Hermitian spatiotemporal modulation, based on the energy redirection from unstable to stable modes by the unidirectional coupling induced by these potentials ... -
Spatiotemporal stabilization of PT-symmetric BAS lasers
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2020)
Conference report
Restricted access - publisher's policyWe propose a compact solution to spatially regularize and temporally stabilize edge emitting (broad area) semiconductor lasers. The scheme relays on the local asymmetries generated by a non-Hermitian potential with a central ... -
Second harmonic generation from an ITO nanolayer: experiment versus theory
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2020)
Conference report
Open AccessWe report a comparative experimental and theoretical study of second harmonic generation from a 20nm-thick indium tin oxide nanolayer in the proximity of the epsilon-near-zero condition. We record the efficiency of the ... -
Stabilized Bright Narrow Beams from Edge-Emitting Lasers
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Restricted access - publisher's policyWe present new edge-emitting laser configurations to improve the laser performance with a double benefit, light localization into a bright narrow beam emission and the suppression of spatiotemporal dynamics. The proposal ... -
Experimental and Theoretical Study of Second Harmonic Generation from an ITO Nanolayer
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Restricted access - publisher's policyWe present an experimental study of second harmonic generation from a 20nm-thick indium tin oxide layer in the proximity of its epsilon-near-zero condition. We report measurements of second harmonic efficiencies as a ... -

Spatial filtering in broad area semiconductor laser using photonic crystal
(2020)
Conference lecture
Restricted access - publisher's policyIn high power regimes, broad area semiconductor lasers usually suffer from poor beam quality due to their asymmetric beam divergence, large beam quality factor (M2) and from the absence of any intrinsic filtering mechanism ... -
Wakes and instabilities of static and freely vibrating cylinders
(Springer, 2019)
Conference report
Open AccessThe flow around static and freely vibrating cylinders are of interest in understanding different phenomena encountered in many practical applications. -
Characteristics and dynamics of crescentic bar events at Castelldefels beach
(Consejo Superior de Investigaciones Científicas (CSIC), 2019)
Conference report
Open AccessCrescentic sand bars have been studied intensively in the last decades, resulting in good knowledge of some of their characteristics, but the processes behind their formation and destruction are not yet clear. This study ... -
The OTree: multidimensional indexing with efficient data sampling for HPC
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessSpatial big data is considered an essential trend in future scientific and business applications. Indeed, research instruments, medical devices, and social networks generate hundreds of petabytes of spatial data per year. ... -
Obtaining directional wave characteristics in front of nearshore field sites
(European Geosciences Union (EGU), 2019)
Conference report

Surface and bulk harmonic generation in the opaque region of GaAs
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
Conference lecture
Restricted access - publisher's policyWe demonstrate second and third harmonic generation from a GaAs substrate, well-bellow the absorption edge, in both transmission and reflection geometries. The pump is tuned at 1064 nm, in the transparency range, while the ...
