LIME Team
The LIght and MEchanics (LIME) team studies the interactions between light and miniature mechanical resonators (micro- or nanomechanical). Its research is therefore positioned in the field of optomechanics, at the interface between light and matter. The team addresses both fundamental questions (quantum behavior of mechanical systems, decoherence phenomena at mesoscopic scales), and applications, notably in the field of optical and mechanical sensors. Thanks to its strong nanotechnology background, LIME ventures into multidisciplinary fields involving semiconductors, fluidics, biophysics and the development of new types of microscopes.
Optomechanical resonator
An optical resonator (in this case, a Fabry-Pérot cavity made up of two mirrors) is fed with incident laser light. The cavity’s rear mirror is mounted on a spring, itself becoming a mechanical resonator. Two resonators, optical and mechanical, are thus coupled.
