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…
