Paper Abstract

We report on the measurement of small stress fluctuations in loaded fused silica fibers using high-Q optical microcavity sensor with whispering-gallery modes. Axial force applied to the spherical whispering-gallery mode microcavity by the fiber attached in the polar area displaced the frequencies of whispering-gallery mode resonances, and enabled high-sensitivity measurement of the stress force variations. With quality factor of integrated microcavity sensor of (2-7)x107, the achieved spectral sensitivity of force measurement was <1x10-8 N/(root)Hz in the 102-103 Hz frequency range and about 2x10-10N/(root)Hz above 104 Hz.
