Fabricating fiber cavity mirror substrates compatible with high coupling efficiency
Michael Caouette-Mansour, Thomas J. Clark, Valeria Mosso Tsedilkina +1
Fiber optical cavities offer small mode volumes and correspondingly strong light-matter interactions in an open Fabry-Perot geometry. However, existing fabrication techniques do no…

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 --…

Detuning-symmetric laser cooling of many mechanical modes with a photothermally modified cavity
Thomas J. Clark, Jiaxing Ma, Jack C. Sankey
We simultaneously cool 100 mechanical modes of a membrane with a photothermally modified optical cavity driven by a single blue-detuned laser. In contrast to radiation pre…
