Development of a new photoplethysmography system and its tests
(Universitat Politècnica de Catalunya, 2018-09-07)
Master thesis
Restricted access - author's decisionA novel set of instrumentation and algorithms for an image based photoplesthymography system for non-invasive and noncontact measurement of vital signs is developed and herein reported. Signal processing was enhanced by ... -
Graphene-based multimode interference device design for optical switching applications
(Universitat Politècnica de Catalunya, 2018-08-27)
Master thesis
Open Access
Covenantee: Vrije Universiteit Brussel / Universiteit GentThe relatively small size and low energy consuming switching potential offered by graphene-based electro-optic and electro-absorption switches has attracted a lot of attention in the photonics community recently and there ... -
Applications of a quantum random number generator to simulations in condense matter physics
(Universitat Politècnica de Catalunya, 2018-10-15)
Master thesis
Open Access
Covenantee: Institut de Ciències Fotòniques (ICFO)We study the importance of the quality of random numbers in Monte Carlo simulations of 2D Ising systems. Simulations are carried out at critical temperature to find the dynamic scaling law of the linear relaxation time. ... -

Covenantee: Universiteit GentGraphene combines a variety of unique properties, including mechanical robustness, transparency and high thermal and electrical conductivity, all together making it a promising material for a wide range of applications, ... -
Surface and bulk harmonic generation in the opaque region of GaAs
(Universitat Politècnica de Catalunya, 2018-09-06)
Master thesis
12 months embargoWe demonstrate second and third harmonic generation from a GaAs substrate, far from the phase matching and well-below the absorption edge, in both transmission and reflection geometries. The pump is tuned in the transparency ... -
Diffuse reflectance spectroscopy characterization of molecular absorption via graphene based photodetectors
(Universitat Politècnica de Catalunya, 2018-09)
Master thesis
60 months embargoThis Master dissertation explores diffuse reflection spectroscopy as a viable tool for analytical chemistry, both quantitatively and qualitatively. In-vitro optical phantoms are created to mimic the turbid diffuse environments ... -
3D and multispectral imaging technology to aid in the diagnosis of skin cancer
(Universitat Politècnica de Catalunya, 2018-09-06)
Master thesis
Restricted access - author's decisionSkin cancer is one of the most frequent cancers in humans. The most important risk factor is UV radiation due to excessive sun. Melanoma is the most aggressive skin cancer and its incidence increases every year. Early ... -
Towards cavity enhanced detection of single ions in the solid-state
(Universitat Politècnica de Catalunya, 2018-09-06)
Master thesis
24 months embargoThe goal of this master thesis was to take initial steps towards cavity-enhanced detection of single rare-earth ions in the solid state. A fibre microcavity set-up for use with Praseodymium-doped nanocrystals was designed, ... -
Development of an image sensor platform for microorganisms in water
(Universitat Politècnica de Catalunya, 2018-09-06)
Master thesis
Restricted access - confidentiality agreementIn this thesis, we demonstrate the correct operation of a fluorescence sensor designed for the analysis of water samples, in concrete phytoplankton levels and microorganism counting. The system, based on different techniques ... -
Effect of stimulus unpredictability in time and magnitude on the vergence system
(Universitat Politècnica de Catalunya, 2018-09-29)
Master thesis
Restricted access - author's decisionPurpose: To study the influence of stimulus predictability (in magnitude and time) and subject?s expertise in vergence facility test in vergence latency times. Methods: Twenty-seven asymptomatic patients were evaluated ... -
Solitons in non-linear ring micro-resonators
(Universitat Politècnica de Catalunya, 2018-09-06)
Master thesis
Open AccessWe studied with the LugiatoLefever spatiotemporal formalism the existence, formation and dynamics of solitons in non-linear Kerr micro-resonators. For anomalous and normal dispersion we find different types of solitons, ... -
Laser based transmitter for 5G networks
(Universitat Politècnica de Catalunya, 2018-09-06)
Master thesis
Open AccessIn our work, we searched a low-cost implementation of a laser-based transmitter for 5G communication. In particular, we designed a RF circuit for antenna communication and we explored the possibility of using a FPGA device ...
