Abstract (EN): In this work, it is demonstrated a fiber ring resonator connected to an interrogation system usually implemented on a cavity ring-down technique. A long-period grating (LPG) was inserted in the resonant cavity, being operated as a curvature sensor. The experimental results demonstrate that using this setup, different sensitivities can be achieved in terms of analyzing decay time over the radius of the curvature and over curvature. The LPG sensor presented higher sensitivity with larger radius of curvature, namely 6.91 s/m. (c) 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:267-270, 2016
