Universidad de Zaragoza Optimized active multicore fiber bending sensor 2018 Access copy available to the general public Unrestricted We present a study of the feasibility of transforming the multicore fiber in a supermode-interference based bending sensor into an active stage. By compensating the antisymmetric supermode losses for high curvatures, fringe visibility is improved and the sensor operating range can be extended. For a given multicore fibre length and Er3+-ion concentration sensor calibration curves allow assessing the bending radius by measuring the visibility as a function of the input pump power. The Er3+-ion concentration, available input pump power and multicore fiber length set the minimum bending radius that could be measured. info:eu-repo/grantAgreement/ES/DGA/FSE info:eu-repo/grantAgreement/ES/MINECO/TEC2014-52642-C2-2 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.687 2018 OPTICS 34 / 95 = 0.358 2018 Q2 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 120 / 293 = 0.41 2018 Q2 T2 0.59 2018 Atomic and Molecular Physics, and Optics 2018 Q1 Electronic, Optical and Magnetic Materials 2018 Q1 Electrical and Electronic Engineering 2018 Q1 Computer Science (miscellaneous) 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-3867-2182 Benedicto, D.
