Niobium Titanium Nitride as a High Tensile Stress Material for Nanomechanics
Korbinian Rubenbauer, Burak E. Bülbüloglu, Thomas Luschmann +6
Over the past decades, high-coherence mechanical resonators have been continuously pushed to new limits, using techniques such as dissipation dilution and clamp-tapering to enhance…
Extracting higher-order nonlinearities in nanomechanical resonators using the backbone relation
Maria Kallergi, Daniel K. J. BoneÃ, Maximilian Seitner +2
Nanomechanical resonators are a powerful platform for studying nonlinear dynamics with high sensitivity and precision. We explore the nonlinear response of a high-Q nanomechanical…
Universal Design Path for Optomechanical Crystals and One-dimensional Photonic Crystals
Berke Demiralp, Nien-Hsuan Lee, Eva M. Weig
We have shown a pattern that connects the refractive index, area and the cavity modes of the optomechanical crystals (OMCs) by the same order function. By keeping the fundamental a…
Reconstructing the system coefficients for coupled harmonic oscillators
Jan Bartsch, Ahmed A. Barakat, Simon Buchwald +3
Physical models often contain unknown functions and relations. In order to gain more insights into the nature of physical processes, these unknown functions have to be identified o…
Precise estimation of the coupling strength between two nanomechanical modes from four Ramsey fringes
Anh Tuan Le, Avishek Chowdhury, Hugo Ribeiro +1
We experimentally determine the coupling strength between two strongly coupled nanomechanical modes using a Ramsey-inspired technique optimized for signals as short as four fringes…
Shape Optimization of Geometrically Nonlinear Modal Coupling Coefficients: An Application to MEMS Gyroscopes
Daniel Schiwietz, Marian Hörsting, Eva Maria Weig +2
Micro- and nanoelectromechanical system (MEMS and NEMS) resonators can exhibit rich nonlinear dynamics as they are often operated at large amplitudes with high quality factors and…
