Broadband Thermal Noise Correlations Induced by Measurement Back-Action
Jiaxing Ma, Thomas J. Clark, Vincent Dumont +1
Modern mechanical sensors increasingly measure motion with precision sufficient to resolve the fundamental thermal noise floor over a broad band. Compared to traditional sensors --…
An optically defined phononic crystal defect
Thomas J. Clark, Simon Bernard, Jiaxing Ma +2
We demonstrate a mechanical crystal with an optically programmable defect mode. By applying an optical spring to a single unit cell of a phononic crystal membrane, we smoothly tran…
High-Power Quantum-Limited Photodiode and Classical Laser Noise Squashing
Vincent Dumont, Jiaxing Ma, Eamon Eagan +1
To benefit high-power interferometry and the creation of low-noise light sources, we develop a simple lead-compensated photodetector enabling quantum-limited readout from 0.3 mW to…
Asymmetry-Based Quantum Backaction Suppression in Quadratic Optomechanics
Vincent Dumont, Hoi-Kwan Lau, Aashish A. Clerk +1
As the field of optomechanics advances, quadratic dispersive coupling (QDC) promise an increasingly feasible class of qualitatively new functionality. However, the leading QDC geom…
Cavity-enhanced absorption sensing with robust sideband locking
Fernanda C. Rodrigues-Machado, Pauline Pestre, Vincent Dumont +5
We present a simple, continuous, cavity-enhanced optical absorption measurement technique based on high-bandwidth Pound-Drever-Hall (PDH) sideband locking. The technique provides a…
Monitored wet-etch removal of individual dielectric layers from high-finesse Bragg mirrors
Simon Bernard, Thomas J. Clark, Vincent Dumont +2
It is prohibitively expensive to deposit customized dielectric coatings on individual optics. One solution is to batch-coat many optics with extra dielectric layers, then remove la…
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…
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…
