EPFL

Ecole Polytechnique Fédérale de Lausanne – presentation

EPFL is Europe’s most cosmopolitan technical university. It receives students, professors and staff from over 120 nationalities. With both a Swiss and international calling, it is therefore guided by a constant wish to open up; its missions of teaching, research and partnership impact various circles: universities and engineering schools, developing and emerging countries, secondary schools and gymnasiums, industry and economy, political circles and the general public.

EPFL is composed of 5 schools and 2 colleges: School of Basic Sciences, School of Life Sciences, School of Engineering, School of Architecture, Civil and Environmental Engineering, School of Computer and Communication Sciences, College of Management of Technology and College of Humanities.

This ITN cQOM project is hosted by the EPFL at the Laboratory of Photonics and Quantum Measurements, K-Lab, lead by Prof. Tobias Kippenberg. Research in the group is centered around the use of optical microresononators for highly sensitive measurements of mechanical motion, frequency or biophysical molecules. Since its inception the group has been active and made several widely recognized contributions in three fields: Cavity Optomechanics, Monolithic Optical Frequency Comb and Ultra Sensitive Biophysical Recognition.

Cavity Optomechanics

A major field of study in the group is the use of optomechanical microresonators to demonstrate optomechanical phenomena experimentally and to demonstrate quantum measurement theory in an experimental setting. In this context, the group experimentally demonstrated for the first time a novel laser cooling method which uses radiation pressure backaction in 2006. Moreover the group has experimentally demonstrated the regime of resolved sidebands, which is a prerequisite to ground state cooling. Combining cryogenic precooling using a helium-3 exchange gas with backaction laser cooling, they are exploring the possibility of ground state cooling a micromechanical oscillator, which has been of interest in Quantum Physics for almost a decade.
