Thermal intermodulation noise in cavity-based measurements
Sergey A. Fedorov, Alberto Beccari, Amirali Arabmoheghi +3
Thermal frequency fluctuations in optical cavities limit the sensitivity of precision experiments ranging from gravitational wave observatories to optical atomic clocks. Convention…
Fractal-like mechanical resonators with soft-clamped fundamental mode
Sergey A. Fedorov, Alberto Beccari, Nils J. Engelsen +1
Self-similar structures occur naturally and have been employed to engineer exotic physical properties. Here we show that acoustic modes of a fractal-like system of tensioned string…
Thermo-refractive noise in silicon nitride microresonators
Guanhao Huang, Erwan Lucas, Junqiu Liu +5
Thermodynamic noise places a fundamental limit on the frequency stability of dielectric optical resonators. Here, we present the characterization of thermo-refractive noise in phot…
Clamp-tapering increases the quality factor of stressed nanobeams
Mohammad J. Bereyhi, Alberto Beccari, Sergey A. Fedorov +5
Stressed nanomechanical resonators are known to have exceptionally high quality factors () due to the dilution of intrinsic dissipation by stress. Typically, the amount of dissi…
Generalized dissipation dilution in strained mechanical resonators
Sergey A. Fedorov, Nils J. Engelsen, Amir H. Ghadimi +4
Mechanical resonators with high quality factors are of relevance in precision experiments, ranging from gravitational wave detection and force sensing to quantum optomechanics. Bea…
Ultralow-power chip-based soliton microcombs for photonic integration
Junqiu Liu, Arslan S. Raja, Maxim Karpov +6
The generation of dissipative Kerr solitons in optical microresonators has provided a route to compact frequency combs of high repetition rate, which have already been employed for…
