Silva, Francisco José Maia da (Date of defense: 2016-02-29)
Devising new tools that expand our capabilities to sense and manipulate the world enables much of the scientific and technological progress around us. For example, light is increasingly more important as a tool for humanity. ...
Behbood, Naeimeh (Date of defense: 2015-04-17)
(English) This thesis describes the generation of macroscopic spin singlets in a cold atomic ensemble by performing quantum non-demolition measurement. Toward this goal we have implemented a realtime shot-nose limited ...
Agarwal, Hitesh (Date of defense: 2023-01-23)
(English) Despite the extensive research in the semiconductor industry, Moore’s law is finally slowing down due to increased complexity. Hence, intense efforts are being carried out to explore hybrid solutions by adding ...
Weber, Peter (Date of defense: 2016-12-02)
In recent years, mechanical resonators based on graphene have attracted considerable interest as nanoelectromechanical systems (NEMS). Graphene NEMSs allow for exceptional properties such as high mechanical strength, high ...
Badioli, Michela (Date of defense: 2015-12-04)
Since its discovery in 2004, graphene, a one-atom-thick layer of carbon atoms arranged in a hexagonal lattice, has attracted huge interest from the scientific community due to its extraordinary electronic, mechanical, and ...
Baudisch, Matthias (Date of defense: 2017-07-12)
High-energy, few-cycle, mid-lR radiation sources featuring high pulse repetition rates are of tremendous interest for a variety of strong-field physics and attoscience applications. Such systems could be used in combination ...
Elu Etxano, Ugaitz (Date of defense: 2022-05-03)
In the last decades, intense carrier-envelope-phase-stable (CEP-stable) and near-single-cycle, coherent mid-infrared sources have become charming for a variety of applications in physics, chemistry and biology. In particular, ...
Parsa, Shahrzad (Date of defense: 2018-07-24)
Ultrafast picosecond coherent sources in the near-to-mid-infrared (IR) spectral range are of great interest for a variety of applications such as pump-probe spectroscopy, remote sensing, photobiology and novel upconversion ...
Samanta, Goutam Kumar (Date of defense: 2009-07-01)
This thesis presents the development of a new class of high-power, continuous-wave (cw) optical parametric oscillators (OPOs) with extended tunability from visible to near-infrared (near-IR). While lasers have been in use ...
Sánchez Bautista, Enrique (Date of defense: 2015-11-26)
High-power, stable, high-repetition-rate, picosecond ultraviolet (UV) sources are of crucial importance for a variety of applications, such as atmospheric sensing, spectroscopy or optical data storage. Further, precise ...
Chaitanya Kumar, Suddapalli (Date of defense: 2012-01-18)
High-power, continuous-wave (cw), mid-infrared (mid-IR) laser sources are of interest for variety of applications such as trace gas detection and remote sensing, which require broad spectral coverage to address the most ...
Martínez Cercós, Daniel (Date of defense: 2023-06-21)
(English) There is currently significant scientific and technological interest in ultrathin materials, with at least one dimension in the nm range or even smaller, since they possess features not achievable with their ...
Giovannella, Martina (Date of defense: 2019-06-04)
Hybrid diffuse optical devices allows for the non-invasive and continuous monitoring of the cerebral haemodynamics and metabolism. Such devices can be portable and are relatively inexpensive, therefore available at the ...
Farzam, Parisa (Date of defense: 2014-10-14)
Noninvasive measurement of hemodynamics at the microvascular level may have a great impact on oncology in clinics for diagnosis, therapy planning and monitoring, and, in preclinical studies. To this end, diffuse optics is ...
Mireles Núñez, Miguel Adrián (Date of defense: 2018-10-24)
A pre-clinical mouse model of human clear cell renal cell carcinoma (ccRCC) was employed as a method to study the prognostic and theranostic potential of two, non-invasive, deep tissue, diffuse optical techniques, namely ...
Bermúdez Ureña, Esteban (Date of defense: 2017-07-17)
The field of photonics comprehends the generation, manipulation and detection of light (photons). Over the past decades, it has underpinned many of the technological advances upon which we rely on a daily basis, from our ...
Pérez Rosas, Juan Miguel (Date of defense: 2020-07-28)
