Asymmetric soliton mobility in competing linear-nonlinear parity-time-symmetric lattices
(2016-09-15)
Article
Restricted access - publisher's policyWe address the transverse mobility of spatial solitons in competing parity-time-symmetric linear and nonlinear lattices. The competition between out-of-phase linear and nonlinear lattices results in a drastic mobility ... -

Binocular open-view system to perform estimations of aberrations and scattering in the human eye
(2015-11-10)
Article
Open AccessWe present a system that integrates a double-pass (DP) instrument and a Hartmann-Shack (HS) wavefront sensor to provide information not only on aberrations, but also on scattering occurring in the human eye. A binocular ... -
Brightness enhancement in Non-Hermintian VCSELs
(Optical Society of American (OSA), 2019)
Conference report
Restricted access - publisher's policyVertical Cavity Surface Emitting lasers (VCSELs) are compact and efficient light sources useful for a variety of applications. However, due to lack of a transverse mode control mechanism, such lasers suffer from poor spatial ... -
Calibration of an optical probe
(Universitat Politècnica de Catalunya / Institut National Polytechnique de Grenoble, 2009)
Master thesis (pre-Bologna period)
Restricted access - author's decisionThe aim of the experiment is to calibrate a monofiber optical probe, used in two phase gas-liquid flow, to a speed of 40 m/s. To measure the bubble velocity, the optical probe requires calibration. This procedure consists ... -
Canvis relatius en la refracció perifèrica en escolars.
(Universitat Politècnica de Catalunya, 2015-06-29)
Bachelor thesis
Open AccessDiversos estudis han demostrat que la retina perifèrica juga un paper important en la determinació del creixement de l’ull, que té un efecte sobre el creixement de la longitud axial, i pot participar en el procés ... -
Canvis relatius en la refracció perifèrica en infants preescolars.
(Universitat Politècnica de Catalunya, 2015-06-29)
Bachelor thesis
Open AccessNombrosos estudis han demostrat que el desenvolupament de l’error refractiu és un procés manipulable, fins i tot un cop finalitzat el procés d’emmetropització. S’ha suggerit que quan es fa coincidir una imatge enfocada ... -
Comparison of OFDM with single carrier in high-data rate optical communication systems
(Universitat Politècnica de Catalunya, 2011-12-23)
Master thesis (pre-Bologna period)
Open AccessEnglish: Analysis of Orthogonal FDM modulation for long-haul optical communications, and validation of its performances over conventional transmission. -
Conformational changes in matrix-isolated 6-methoxyindole: Effects of the thermal and infrared light excitations
(AIP, 2016-03-25)
Article
Open AccessConformational changes induced thermally or upon infrared excitation of matrix-isolated 6-methoxyindole were investigated. Narrowband near-infrared excitation of the first overtone of the N–H stretching vibration of each ... -
Coupling plasmons and dyakonons
(2012-06-01)
Article
Restricted access - publisher's policyWe study the coupling of plasmons and Dyakonov surface waves propagating at the interfaces between isotropic-birefringent-metal layered structures. Efficient coupling is shown to occur with a proper choice of the crystal ... -
Creació i planificació estratègica d'una òptica en època de canvis
(Universitat Politècnica de Catalunya, 2014-12-12)
Master thesis
Open AccessEn aquest Treball de Final de Màster, es vol portar a terme un pla de negoci per implantar una òptica en un poble costaner de Catalunya (Calafell). Explicarem i desenvoluparem tots els procediments i estratègies per convertir ... -
Cyclic concentrator, carpet cloaks and fisheye lens via transformation plasmonics
(IOP, 2016-04-01)
Article
Open AccessWe first review basic equations of plasmonics in anisotropic media. We recall the origin of Maxwell’s gradient index fisheye lens. We then apply tools of transformation optics to the design of a cyclic concentrator and ... -
Design, implementation and test of a routine Light Sheet fluorescence microscope
(Universitat Politècnica de Catalunya, 2015-06)
Bachelor thesis
Open AccessMicroscopy has revealed an astonishing new world that was previously invisible to our eyes. Unfortunately, we still have very little knowledge of how life actually works, and for that reason new powerful microscopy techniques ... -

Disseny de lents progressives
(Universitat Politècnica de Catalunya, 2014-02)
Master thesis
Restricted access - author's decisionPresbyopia starts to show up at the age of 40. The lens of the eye loses its flexibility to the point where we can no longer accommodate clearly in near vision. Progression-addition lenses correct the lack of accommodation ... -

Dynamic versus Anderson wave-packet localization
(2015-06-18)
Article
Open AccessWe address the interplay between two fundamentally different wave-packet localization mechanisms, namely, resonant dynamic localization due to collapse of quasienergy bands in periodic media and disorder-induced Anderson ...
