Gas cooling of test masses for future gravitational-wave observatories
Christoph Reinhardt, Alexander Franke, Jörn Schaffran +2
Recent observations made with Advanced LIGO and Advanced Virgo have initiated the era of gravitational-wave astronomy. The number of events detected by these "2nd Generation" (2G)…

Flexure-Tuned Membrane-at-the-Edge Optomechanical System
Vincent Dumont, Simon Bernard, Christoph Reinhardt +3
We introduce a passively-aligned, flexure-tuned cavity optomechanical system in which a membrane is positioned microns from one end mirror of a Fabry-Perot optical cavity. By displ…

Swept-Frequency Drumhead Mechanical Resonators
Raphael St-Gelais, Simon Bernard, Christoph Reinhardt +1
We demonstrate a high-Q () swept-frequency membrane mechanical resonator achieving octave resonance tuning via an integrated heater and an unprecedented accelerat…
