Universitat Politècnica de Catalunya
L'Institut de Ciències Fotòniques té com a objectius la recerca, la docència i l'incentiu del sector industrial en l'àmbit de les ciències de la llum i de totes les disciplines en les quals la fotònica tingui incidència, com ara les nanotecnologies òptiques, les tecnologies de la informació, les biotecnologies, les ciències de la salut i de la vida, les tecnologies de la informació quàntica i els sistemes làser. Referent únic a Europa per les seves característiques, l'ICFO es va crear com a fundació privada el març de 2002, constituïda inicialment per la UPC i el Departament d'Universitats, Recerca i Societat de la Informació (DURSI) de la Generalitat de Catalunya.

(English) The fundamental science and technological applications of light-matter interactions on nanometer length scales form the field of study known as nanophotonics. Explorations in nanophotonics expand our understanding ...
(English) This thesis, mostly experimental, is based on two fundamental pillars: nonlinear interferometers and Optical Coherence Tomography (OCT). Nonlinear interferometers are a class of interferometers that exhibit ...
(English) Besides its relevant fundamental interest, the in-depth understanding of light-matter interactions at the nanoscale has a profound impact on modern technological applications in diverse areas including ...
(English) The interface between light and cold atomic ensembles is a fundamental platform to unravel the quantum world and develop quantum technological applications. Its success relies on the simple idea that the efficiency ...
(English) Highly transparent optical surfaces with anti-reflection (AR) and self-cleaning properties have the potential to increase performance in a wide range of applications, such as display screens, photovoltaic cells ...
(English) In the intensive care, the multimodal monitoring of the patient is crucial. The systemic physiology is routinely and comprehensively monitored but the practical monitoring of the brain is lacking. Hybrid diffuse ...
(English) In this thesis, we study the optimization of operational tasks that involve the manipulation of quantum resources. In most cases, such optimizations are aided by understanding the geometric properties of the ...
(English) The modern understanding of physics is deeply linked with the concept of information. The revival of the study of quantum mechanics in the form of quantum information is just an example of a more general trend ...
(English) In this work we propose and demonstrate cavity-enhanced polarization rotation to detect magnetic effects in transparent media with greater sensitivity at equal optical disturbance to the atomic medium. We use the ...
