title: Bottle microresonator with actively stabilized evanescent coupling.
abstract: The evanescent coupling of light between a whispering-gallery-mode bottle microresonator and a subwavelength-diameter coupling fiber is actively stabilized by means of the Pound-Drever-Hall technique. We demonstrate the stabilization of a critically coupled resonator with a control bandwidth of 0.1 Hz, yielding a residual transmission of (9±3)×10(-3) for more than an hour. Simultaneously, the frequency of the resonator mode is actively stabilized.
