FUTURE ATOMIC CLOCK TECHNOLOGY (FACT)
Date du début: 1 oct. 2013, Date de fin: 30 sept. 2017,
During the last decades atomic clocks and frequency standards have become an important resource for advanced economies with impact ranging from satellite navigation (GPS, GLONASS, Galileo) to high speed communication networks, where they ensure synchronisation of data packets at ever higher bit rates. In this field the wake of the new millennium has been marked by the invention of frequency comb t ...

Interfacing Quantum Optical, Electrical, and Mechanical Systems (iQUOEMS)
Date du début: 1 oct. 2013, Date de fin: 30 sept. 2016,
This project aims at the efficient realization of quantum interfaces for high-fidelity conversion and coherent manipulation of quantum states of phonons and of photons at vastly distinct wavelengths. We will consider different experimental platforms, e.g. photonic crystal cavities, nonlinear crystalline resonators, graphene-based nanoelectromechanical systems, and nanomembranes, with the aim of im ...

Cavity Quantum Optomechanics (cQOM)
Date du début: 1 juin 2012, Date de fin: 31 mai 2016,
Over the past year a new research field has emerged: cavity Optomechanics which brings the quantum regime of mechanical oscillators in reach and may allow to explore new fundamental measurements concepts, may lead to novel transducers and test quantum mechanics on a macroscopic scale. In this research field, which utilizes mechanical oscillators coupled to laser fields, Europe has played a pioneer ...

Simulators and Interfaces with Quantum Systems (SIQS)
Date du début: 1 mai 2013, Date de fin: 30 avr. 2016,
The overarching goal of our project is to develop systems based on direct and deterministic interactions between individual quantum entities, which by involving large-scale entanglement can outperform classical systems in a series of relevant applications.We plan to achieve that by improving technologies from atomic, molecular and optical physics as well as from solid-state physics, and by develop ...

Soliton Kerr Physics in microresonator-bases frequency combs (SOLICOMB)
Date du début: 1 mars 2014, Date de fin: 29 févr. 2016,
Optical frequency combs provide equidistant markers and enable connecting optical to radio frequencies (RF) and vice versa. Today, frequency combs are becoming enabling tools for several applications in metrology and spectroscopy. A new class of Kerr-frequency comb sources, based on parametric frequency conversion in optical silica micro-resonators, has been demonstrated in 2007 by the host group. ...

Quantum Coherence and Decoherence in Cavity Optomechanics (QCDOM)
Date du début: 1 déc. 2013, Date de fin: 30 nov. 2015,
Rapid progress in the field of optomechanics has undergone a paradigm shift in the last two years. It is now possible to use light to prepare and sense the quantum ground state of a nanomechanical oscillator. Alongside parallel developments in electromechanics, this success marks the emergence of a third wave of quantum technology based on mechanical systems, following in the footsteps of atomic ...

Towards Neutral-atom Space Optical Clocks: Development of high-performance transportable and breadboard optical clocks and advanced subsystems (SOC2)
Date du début: 1 mars 2011, Date de fin: 31 oct. 2015,
"A range of new applications will be enabled by ultra-precise optical clocks, some of which by using them in space, near or far distant from Earth. They cover the fields of fundamental physics (tests of General Relativity), time and frequency metrology (comparison of distant terrestrial clocks, operation of a master clock in space), geophysics (mapping of the gravitational potential of the Earth), ...

Microresonator based Frequency Comb Generators (µComb)
Date du début: 1 juin 2010, Date de fin: 31 mai 2014,
Optical frequency combs have revolutionized optical frequency metrology in just a few years. They have made it possible to directly count light field oscillations of several 100 million cycles per second. Traditionally they have been created with mode locked ultra short pulse lasers. In this project we propose to investigate frequency comb generation based on monolithic micro resonators. As recent ...

"Cavity optomechanics is a flourishing research field concerned with the study of macroscopic objects in a regime where quantum mechanical effects become apparent. A strong interaction between the optical field and the mechanical motion of optomechanical resonators, usually mediated by radiation pressure, enables both new photonic technologies as well as fundamental experiments that are at the hea ...

"Optical frequency combs have become pivotal tools in a wide range of studies, from metrology, gas sensing to astronomy. In 2007 the host laboratory has demonstrated an entirely new approach to generate frequency combs from optical micro-resonators. The physical process responsible for the comb generation is parametric four-wave mixing.The micro-resonator frequency combs not only represent conside ...
