Low Noise Opto-Electro-Mechanical Modulator for RF-to-Optical Transduction in Quantum Communications
Michele Bonaldi, Antonio Borrielli, Giovanni Di Giuseppe +7
In this work, we present an Opto-Electro-Mechanical Modulator (OEMM) for RF-to-optical transduction realized via an ultra-coherent nanomembrane resonator capacitively coupled to an…
Optical self-cooling of a membrane oscillator in a cavity optomechanical experiment at room temperature
P. Vezio, M. Bonaldi, A. Borrielli +5
Thermal noise is a major obstacle to observing quantum behavior in macroscopic systems. To mitigate its effect, quantum optomechanical experiments are typically performed in a cryo…
The construction and characterization of MgO transmission dynodes
H. W. Chan, V. Prodanović, A. M. M. G. Theulings +5
In this work we demonstrate that ultra-thin (5 and 15 nm) MgO transmission dynodes (tynodes) with sufficient high transmission electron yield (TEY) can be constructed. These tynode…
Silicon-nitride nanosensors toward room temperature quantum optomechanics
Enrico Serra, Antonio Borrielli, Francesco Marin +9
Observation of quantum phenomena in cryogenic, optically cooled mechanical resonators has been recently achieved by a few experiments based on cavity optomechanics. A well-establis…
Quantum motion of a squeezed mechanical oscillator attained via a optomechanical experiment
P. Vezio, A. Chowdhury, M. Bonaldi +7
We experimentally investigate a mechanical squeezed state realized in a parametrically-modulated membrane resonator embedded in an optical cavity. We demonstrate that a quantum cha…
Probing quantum gravity effects with quantum mechanical oscillators
M. Bonaldi, A. Borrielli, A. Chowdhury +13
Phenomenological models aiming to join gravity and quantum mechanics often predict effects that are potentially measurable in refined low-energy experiments. For instance, modified…
Calibrated quantum thermometry in cavity optomechanics
A Chowdhury, P Vezio, M Bonaldi +9
Cavity optomechanics has achieved the major breakthrough of the preparation and observation of macroscopic mechanical oscillators in peculiarly quantum states. The development of r…
Silicon Nitride MOMS Oscillator for Room Temperature Quantum Optomechanics
Enrico Serra, Bruno Morana, Antonio Borrielli +6
Optomechanical SiN nano-oscillators in high-finesse Fabry-Perot cavities can be used to investigate the interaction between mechanical and optical degree of freedom for ultra-sensi…
Quantum nondemolition measurement of optical field fluctuations by optomechanical interaction
A. Pontin, M. Bonaldi, A. Borrielli +7
According to quantum mechanics, if we keep observing a continuous variable we generally disturb its evolution. For a class of observables, however, it is possible to implement a so…
Microfabrication of large area high-stress silicon nitride membranes for optomechanical devices
E. Serra, M. Bawaj, A. Borrielli +16
In view of the integration of membrane resonators with more complex MEMS structures, we developed a general fabrication procedure for circular shape SiN membranes using Deep Re…
Dynamical two-mode squeezing of thermal fluctuations in a cavity opto-mechanical system
A. Pontin, M. Bonaldi, A. Borrielli +7
We report the experimental observation of two-mode squeezing in the oscillation quadratures of a thermal micro-oscillator. This effect is obtained by parametric modulation of the o…
