Real-time tissue-equivalent measurement of individual clinical radiotherapy pulses
Fernanda C. Rodrigues-Machado, Katherine Szabo, Jingyi Bian +5
We apply the precision tools of cavity-enhanced absorption sensing to clinical oncology, demonstrating a dosimeter paradigm in which a centimeter-scale volume of water serves as a…
Radiation hardness of open Fabry-Perot microcavities
Fernanda C. Rodrigues-Machado, Erika Janitz, Simon Bernard +6
High-finesse microcavities offer a platform for compact, high-precision sensing by employing high-reflectivity, low-loss mirrors to create effective optical path lengths that are o…
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…
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…
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…
