Sensing with coupled-core optical fiber Bragg gratings

[EN] Sensitive bending and vibration sensors based on a coupled-core optical fiber with Bragg gratings are proposed and demonstrated. The interrogation of such sensors is cost effective without comprising the sensors performance.This work was supported by the Spanish Ministry of Science and Innovation under projects No. PGC2018-101997-B100 and RTI2018-0944669-BC31 and the Universitat Politècnica de València with the scholarship PAID-01-18.Flores-Bravo, JA.; Madrigal-Madrigal, J.; Zubia, J.; Margulis, W.; Sales Maicas, S.; Villatoro, J.
