Controlling light in scattering media using ultrasound modulation
(Universitat Politècnica de Catalunya, 2022-07-21)
Master thesis
Open Access
Covenantee: Universitat de BarcelonaLight-based methods are fundamental in biology and biomedical sciences. They allow for non-invasive diagnosis and localized treatments with resolutions down to the sub-cellular level. However, light scattering inside ... -

(Universitat Politècnica de Catalunya, 2022-07-01)
Conference lecture
Open AccessSe presentan los resultados obtenidos de la medida de la BRDF (Bidirectional Reflectance Distribution Function) espectral de tres muestras translúcidas con distintas áreas de iluminación. Como ya se demostró en un trabajo ... -
Estudio sobre la optimización de la detección del efecto Raman frente a la fluorescencia: aplicación a obras de arte
(Universitat Politècnica de Catalunya, 2011-11-02)
Master thesis (pre-Bologna period)
Open AccessEnglish: Nowadays, Raman spectroscopy has become a very important tool for identifying chemical compounds and their molecular structures since it is non-destructive, has null or near null requirements of sample preparation, ... -
Fabricación de dispositivos fotónicos integrados
(Universitat Politècnica de Catalunya, 2017-10)
Bachelor thesis
Open AccessThe project consists of the design and manufacture of photonic crystals based on macroporous silicon. By means of a lithography we can engrave a pattern on the substrate of the silicon wafers in which we will mark the place ... -
Mesures de dispersió òptica amb detecció de segon harmònic. Anàlisi teòrica
(Universitat Politècnica de Catalunya, 2009-02)
Master thesis (pre-Bologna period)
Open AccessDegut a l’ambició en els objectius s’ha realitzat aquest PFC entre dos estudiants. Tot i la naturalesa compartida de la memòria cal considerar a cadascun responsable d’una vessant diferenciada. La part analítica està ... -

Multi-User MIMO for visible light communications
(Universitat Politècnica de Catalunya, 2016-09)
Bachelor thesis
Open AccessThe lighting is going through revolution. The use of Light Emitting Diodes (LEDs) has greatly increased during the last few years, meanwhile incandescent and fluorescent lamps have become obsolete. The LEDs, apart from ... -
ONU optimal gain and position of the distribution element in Rayleigh-limited WDM and TDM PONs with reflective ONU
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Conference report
Restricted access - publisher's policyThe influence of the distribution element position in PONs is reported. Best Crosstalk-to-Signal ratio (C/S) is achieved if it is placed either in the ONU or OLT vicinity with optimum ONU gain depending of the MUX position -
Seeing through smoke: modelling light scattering in irregular media
(Universitat Politècnica de Catalunya, 2022-09-08)
Master thesis
Open AccessA T-Matrix method has been implemented and used to calculate the propagation properties for multiple types of irregular particles, which plays an important role in light propagation through turbid media such as smoke or ... -
Stimulated Raman scattering and second harmonic generation from a Nd : Y V 04 laser at 1064nm to generate 587nm
(Universitat Politècnica de Catalunya, 2011-07-15)
Master thesis
Open AccessEnglish: We have investigated a light generation at 587 nm based on a combination of two nonlinear processes, stimulated Raman scattering (SRS) in Nd : GdV O4 and second harmonic generation (SHG) in BBO, which efficiently ... -
