Titre : Nanotechnology as the promise for the personalised diabetes medicine

Abstract : Over the past ten years, microwave optomechanics, which studies the interactions between electromagnetic fields confined in a microwave cavity and micro-/nano-electromechanical systems (MEMS or NEMS), becomes a flourishing research field. It inherits rich physics from optomechanics and enables to integrate NEMS with other systems on a chip. It provides an access to cool down NEMS to the quantum ground state, to study the nonlinearity of NEMS, and to perform on-chip thermometry. In this presentation, a classical electrical circuit model is used to introduce basic principles of microwave optomechanics. A direct comparison between classical mode and standard quantum treatment gives the features which are truly quantum, and those which are not. Then, I will also present our experimental activities in integrating silicon nitride mechanical oscillator with microwave optomechanical platform, including mechanical properties of NEMS and microwave engineering. Based on this platform, we achieved several devices (e.g. thermometry on-chip, tunable microwave filters) serving for classical and quantum engineering and delivered a special tool to explore fundamental research.
