Electrically Driven Varifocal Silicon Metalens
Adeel Afridi, Josep Canet-Ferrer, Laurent Philippet +3
Optical metasurfaces have shown to be a powerful approach to planar optical elements, enabling an unprecedented control over light phase and amplitude. At that stage, where wide va…
Resolved Sideband Cooling of a Levitated Nanoparticle in the Presence of Laser Phase Noise
Nadine Meyer, Andres de los Rios Sommer, Pau Mestres +4
We investigate the influence of laser phase noise heating on resolved sideband cooling in the context of cooling the center-of-mass motion of a levitated nanoparticle in a high-fin…
Optimal Feedback Cooling of a Charged Levitated Nanoparticle with Adaptive Control
Gerard P. Conangla, Francesco Ricci, Marc T. Cuairan +3
We use an optimal control protocol to cool one mode of the center of mass motion of an optically levitated nanoparticle. The feedback technique relies on exerting a Coulomb force o…
