Atomic quantum metrology with narrowband entangled and squeezed states of light
The use of light, especially of laser light, is in many cases the most sensitive way to perform measurements. However, the highest sensitivity that can be achieved with laser light as probe is bounded by the standard quantum ...
Nanoscale Coherent Control. Ultrafast dynamics of single molecules, individual light harvesting complexes and discrete nanoantennas at room temperature.
Ultrafast pulses allow observation of molecular dynamics with femtosecond time resolution through pump probe experiments. However, averaging over an ensemble of molecules tends to wash out phase sensitive information, ...
Control of optical fields and single photon emitters by advanced nanoantenna structures
Un tema central en la ciencia y la tecnología es la exploración y explotación de sistemas cada vez más pequeños por medio de técnicas ópticas. A menudo, la longitud de onda viene dictada por el sistema de interés: los ...
Nanoscale spatial control of light in optical antennas
El control dinámico y determinístico de la luz en una escala espacial por debajo de la longitud de onda es un requisito clave para ampliar los conceptos y las funcionalidades de la macro-óptica hasta la escala nanométrica. ...
High-power, fiber-laser-pumped optical parametric oscillators from the visible to mid-infrared
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 ...
Micro-structured ferroelectric superlattice for efficient acousto-optic devices
In this thesis we have investigated and proposed acoustic superLattices (ASLs) made of periodically poled ZX-cut lithium niobate (PPLN) associated ith coplanar electrodes as an effective alternative for surface acoustic ...
Micro-nano structured electro-optic devices in LiNbO3 for communication and sensing
A material that is enabling integrated optics is the ferroelectric crystal Lithium Niobate (LiNbO3), which has excellent electro-optical, acousto-optical and nonlinear optical properties. Moreover, it can be doped with ...
High-power, continuous-wave optical parametric oscillators from visible to near-infrared
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 ...
