The mid-infrared (mid-IR) spectral region, with wavelengths between 3 and 15 µm, is known for a wide range of applications ranging from spectroscopic sensing to thermal imaging. However, despite the strong technological ...
Bodenstedt, Sven (Fecha de defensa: 2024-02-15)
(English) This thesis describes theoretical background, simulations, experimental apparatus and measurements of nuclear spin dynamics via optically pumped magnetometers in unconventional magnetic field regimes. It is divided ...
Icaza Astiz, Yannik Alan de (Fecha de defensa: 2015-01-27)
To measure quantum features in a classical world constrains us to extend the classical technology to the limit, inventing and discovering new schemes to use the classical devices, while reducing and filtering the sources ...
Tepsic, Slaven (Fecha de defensa: 2021-07-07)
Mechanical resonators based on low dimensional materials have attracted a lot of attention due to their remarkable properties. Their ultra-low mass and high Q factors make them exceptional sensors, offering new possibilities ...

Organic photovoltaic (OPV) technology has emerged as a potential cost-effective solution to produce electrical energy. The foreseen low manufacturing costs combined with features as semi-transparency or mechanical flexibility ...
Rosales Guzmán, Carmelo G. (Fecha de defensa: 2015-05-22)
Structured light beams, this is, beams whose phase changes from point to point in the transverse plane, provides with an alternative tool to search for new applications, or simply to expand the capabilities of current ...
Svozilík, Jiŕí (Fecha de defensa: 2014-10-17)
Non-classical correlations, usually referred as entanglement, are ones of the most studied and discussed features of Quantum Mechanics, since the initial introduction of the concept in the decade of 1930s. Even nowadays, ...
Canals Casals, Josep (Fecha de defensa: 2018-10-18)
High-power, high-repetition-rate coherent picosecond sources with high beam quality are of great interest for many scientific and technological applications. For example, coherent sources at the ultraviolet (UV) spectrum ...
De Vega Esteban, Sandra (Fecha de defensa: 2020-02-17)
Ever since the advent of modern technology, major developments have come hand in hand with miniaturization and speed of operation. A proof of this is provided by the impressive success of Moore's law, which predicted that ...
Walasik, Wiktor (Fecha de defensa: 2014-10-13)
In this PhD thesis, we study properties of stationary transverse magnetic polarized waves in structures built of a Kerr-type nonlinear dielectric layer, metal and linear dielectric layers. Although these waves, called here ...
