Disordered media with refractive index variations can be found in the atmosphere, the ocean, and in many materials or biological tissues. Several technologies that make use of such random media, as image formation, satellite ...
Donner, Jon Sean (Data de defensa: 2014-05-30)
In the last decades, optics has become central in many applications in modern society. Nano-optics, which studies the behavior of light at the nanoscale, holds promise to do the same. However, when using traditional optical ...
Alloing, Mathieu (Data de defensa: 2014-05-28)
In this thesis, we report experimental evidence of a "gray" condensate of excitons, as predicted theoretically by M. Combescot et al. Most importantly, the condensate is characterized by the macroscopic population of dark ...
Pastorelli, Francesco (Data de defensa: 2013-12-09)
In this century some of our main issues are energy shortage and pollution. This work will briefly describe these problems, proposing a plan of action combining energy saving and different sustainable energy sources. Within ...
Geiselmann, Michael Wolfgang (Data de defensa: 2014-04-10)
The efficient interaction of photons with single quantum emitters like nitrogen vacancy (NV) centres is essential for the elaboration of future integrated quantum optical devices. A promising strategy towards this goal ...
Olarte, Omar E. (Data de defensa: 2014-03-20)
In the quest for better and faster images of cellular and subcellular structures, biology-oriented optical microscopes have advanced significantly in the last few decades. Novel microscopy techniques such as non-linear ...
Huwer, Jan Henning (Data de defensa: 2014-01-29)
One promising approach for future quantum networks is the combination of strings of trapped ions as quantum-information processors with entangled photon pairs produced by spontaneous parametric down conversion (SPDC) to ...
Gieseler, Jan (Data de defensa: 2014-02-03)
Nanotechnology was named one of the key enabling technologies by the European Commission and its tremendous impact was envisioned early by 20th century physicist R.Feynman in his now oft-quoted talk "Plenty of Room at the ...
Napolitano, Mario (Data de defensa: 2014-02-07)
In this manuscript we present an experimental and theoretical investigation of quantum-noise-limited measurement by nonlinear interferometry, or from another perspective, quantum-noise-limited interaction-based measurement. ...
Martínez Sánchez, Ignacio A. (Data de defensa: 2014-04-25)
Almost two centuries after the first observations of Robert Brown, the study of systems ruled by noise has become a significant part of modern physics and other so diverse situations, such as the stock market, personal ...
Sainz, Ana Belén (Data de defensa: 2014-02-10)
In the past century, experimental discoveries have witnessed phenomena in Nature which challenge our everyday classical intuition. In order to explain these facts, quantum theory was developed, which so far has been able ...
Taminiau, Tim Hugo (Data de defensa: 2011-11-22)
The interaction of light with matter is a central topic in both fundamental science and applied technology. At the heart of this interaction lies the absorption or emission of a photon by an electronic transition in for ...
Devi, Kavita (Data de defensa: 2013-10-24)
High-power, continuous-wave (cw) optical parametric oscillators (OPOs), from the ultraviolet (UV) and visible to the near- and mid-infrared (IR) wavelength range, are of interest for a variety of applications such as ...
