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…
Simple High-Bandwidth Sideband Locking with Heterodyne Readout
Christoph Reinhardt, Tina Müller, Jack C. Sankey
We present a robust sideband laser locking technique that is ideally suited for applications requiring low probe power and heterodyne readout. By feeding back to a high-bandwidth v…
Etch-Tuning and Design of Silicon Nitride Photonic Crystal Reflectors
Simon Bernard, Christoph Reinhardt, Vincent Dumont +2
By patterning a freestanding dielectric membrane into a photonic crystal reflector (PCR), it is possible to resonantly enhance its normal-incidence reflectivity, thereby realizing…
Ultralow-Noise SiN Trampoline Resonators for Sensing and Optomechanics
Christoph Reinhardt, Tina Müller, Alexandre Bourassa +1
In force sensing, optomechanics, and quantum motion experiments, it is typically advantageous to create lightweight, compliant mechanical elements with the lowest possible force no…
Enhanced Optomechanical Levitation of Minimally Supported Dielectrics
Tina Müller, Christoph Reinhardt, Jack C. Sankey
Optically levitated mechanical sensors promise isolation from thermal noise far beyond what is possible using flexible materials alone. One way to access this potential is to apply…
