TL;DR: A laser amplitude modulation technique to actively stabilize the critical coupling of a microresonator by controlling the evanescent coupling gap from an optical fiber taper is presented, achieving a stabilization bandwidth of ∼ 20 Hz and an inferred gap stability of better than a picometer/√Hz.

TL;DR: In this article, a device for detecting seismic acceleration including a proof mass; a base for providing a sensor acceleration relative to the proof mass, based on the seismic acceleration; an optical fibre portion operatively connected between the base and the sensor acceleration, a fibre Fabry-Perot interferometer (FFPI) in the optical fiber portion for providing an optical characteristic representative of the fibre tension, and a compensator for applying a compensating tension to the FFPI to compensate for a change of the optical characteristic due to a temperature change.

TL;DR: It is shown that in reflection, the reduced fiber Fabry-Perot linewidth improves the remote system sensitivity to sub-picostrain resolution, which surpasses any other long-distance remote sensing system to date.

TL;DR: In this paper, the authors describe a coincident gravitational wave burst search, where data from the LIGO interferometers are cross-correlated at the time of AURIGA candidate events to identify coincident transients.
