Abstract
The study and control of levitated nano- and micro-objects has gained considerable attention over the last decade owing to its potential to advance both fundamental science and technology. While early levitation experiments made use of optical potentials and weakly absorbing dielectric polarizable particles, the toolbox expanded in recent years to include techniques borrowed from the atom trapping community. The development of electrostatic and magnetic levitation made it possible to overcome excessive photoheating of the trapped specimen and extended levitation to a broader range of particles, including particles with internal degrees of freedom. Furthermore, on-chip integration has been identified as key to interface levitodynamics with other existing technologies, to increase platform robustness and compatibility with cryogenic conditions, and to devise autonomous and portable sensors.
In this presentation we discuss our most recent advances in the development of integrated hybrid
levitation platforms combining planar electrodes with integrated photonics and metaoptics. We introduce different architectures offering further control over the dynamics of levitated nanoparticles, with applications to both ultra-sensitive force sensing and the study of quantum mechanics with large objects. Finally, we discuss how our technology can be extended to the levitation of resonant silicon meta-atoms, opening new opportunities in the field.
Short bio
Romain Quidant received a PhD in Physics (2002) from the University of Dijon, France. He then joined the newly created ICFO in Barcelona as a postdoctoral researcher. In 2006, he was appointed junior Professor (tenure-track) and group leader of the Plasmon NanoOptics group at ICFO. In 2009, he became tenure Professor both at ICFO and ICREA. After nearly 18 years at ICFO, in June 2020, he joined the Mechanical and Process Engineering department (D-MAVT) at ETH Zurich. He is recipient of 3 ERC grants and several international and national prizes. Since January 2022, he serves as the Editor-in-chief of ACSPhotonics (American Chemical Society).
The research of the Quidant’s lab focuses on nano-optics, at the interface between photonics and nanotechnology. It uses the unique optical properties of nanostructures as enabling tools to design solutions to scientific and technological challenges, in a wide set of disciplines, from fundamental physics to biotechnology. This makes its activities highly multidisciplinary, covering both basic and applied research. The most fundamental part is mainly directed towards enhanced light/matter interaction and optomechanics. From a more applied standpoint, his team investigates new strategies to control light and heat at the nanometer scale for biomedical applications, including lab-on-a-chip technology, and for reconfigurable planar optics.
