Room-temperature quantum optomechanics using an ultralow noise cavity
Tobias Kippenberg, Guanhao Huang, Alberto Beccari, Nils Johan Engelsen
At room temperature, mechanical motion driven by the quantum backaction of light has been observed only in pioneering experiments in which an optical restoring force controls the oscillator stiffness1,2. For solid-state mechanical resonators in which oscil ...
Berlin2024Ultrahigh-quality-factor micro- and nanomechanical resonators using dissipation dilution
Tobias Kippenberg, Alberto Beccari, Nils Johan Engelsen
Mechanical resonators are widely used in sensors, transducers and optomechanical systems, where mechanical dissipation sets the ultimate limit to performance. Over the past 15 years, the quality factors in strained mechanical resonators have increased by f ...
Berlin2024Metasurface-stabilized optical microcavities
Cavities concentrate light and enhance its interaction with matter. Confining to microscopic volumes is necessary for many applications but space constraints in such cavities limit the design freedom. Here we demonstrate stable optical microcavities by cou ...
NATURE PORTFOLIO2023NbN films with high kinetic inductance for high-quality compact superconducting resonators
Edoardo Charbon, Pasquale Scarlino, Fabrizio Minganti, Simone Frasca, Marco Scigliuzzo, Vincent Jean Yves Jouanny, Fabian Oppliger, Roberto Musio
Niobium nitride (NbN) is a particularly promising material for quantum technology applications, as it shows the degree of reproducibility necessary for large-scale superconducting circuits. We demonstrate that resonators based on NbN thin films present a o ...
2023Fabrication Of Lithium Niobate Bulk Acoustic Resonator For 5G Filters
Luis Guillermo Villanueva Torrijo, Annalisa De Pastina, Soumya Yandrapalli, Victor Plessky, Muhammad Faizan
This work presents the fabrication of a MEMS resonant device which addresses the need for high quality and miniaturized RF filters in the 3-6 GHz range for 5th generation (5G) mobile networks. The 4-mask fabrication process is based on the definition of in ...
IEEE2019Free standing and solidly mounted Lamb wave resonators based on Al0.85Sc0.15N thin film
Paul Muralt, Mohammad Fazel Parsapour Kolour, Vladimir Pashchenko
Lamb wave microresonators with wavelengths of 5-8m, vibrating in the S0 mode, and having 75 electrode pairs were fabricated and characterized. The results were compared to theoretical predictions obtained by finite element simulation. The active material w ...
