Angular displacement readout of a mechanical oscillator with a guided mode resonance
Diego Torres-Barajas, Oscar Angulo, Aman R. Agrawal +2
Measuring the angular displacement of a mechanical oscillator is a ubiquitous task; however, the multimode nature of angular optomechanical coupling makes coherent signal enhanceme…
Sub-ppm Nanomechanical Absorption Spectroscopy of Silicon Nitride
Andrew T. Land, Mitul Dey Chowdhury, Aman R. Agrawal +1
Material absorption is a key limitation in nanophotonic systems; however, its characterization is often obscured by scattering and diffraction loss. Here we show that nanomechanica…
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…
Optomechanics with one-dimensional gallium phosphide photonic crystal cavities
Katharina Schneider, Yannick Baumgartner, Simon Hönl +5
Gallium phosphide offers an attractive combination of a high refractive index ( for vacuum wavelengths up to 4 μm) and a wide electronic bandgap (2.26 eV), enabling optical ca…
Evidence for structural damping in a high-stress silicon nitride nanobeam and its implications for quantum optomechanics
S. A. Fedorov, V. Sudhir, R. Schilling +3
We resolve the thermal motion of a high-stress silicon nitride nanobeam at frequencies far below its fundamental flexural resonance (3.4 MHz) using cavity-enhanced optical interfer…
Near-field integration of a SiN nanobeam and a SiO microcavity for Heisenberg-limited displacement sensing
Ryan Schilling, Hendrik Schütz, Amir Ghadimi +3
Placing a nanomechanical object in the evanescent near-field of a high- optical microcavity gives access to strong gradient forces and quantum-noise-limited displacement readout…
