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. 000079550 536__ $$9info:eu-repo/grantAgreement/ES/DGA/FSE$$9info:eu-repo/grantAgreement/ES/MINECO/TEC2014-52642-C2-2 000079550 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000079550 590__ $$a2.687$$b2018 000079550 591__ $$aOPTICS$$b34 / 95 = 0.358$$c2018$$dQ2$$eT2 000079550 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b120 / 293 = 0.41$$c2018$$dQ2$$eT2 000079550 592__ $$a0.59$$b2018 000079550 593__ $$aAtomic and Molecular Physics, and Optics$$c2018$$dQ1 000079550 593__ $$aElectronic, Optical and Magnetic Materials$$c2018$$dQ1 000079550 593__ $$aElectrical and Electronic Engineering$$c2018$$dQ1 000079550 593__ $$aComputer Science (miscellaneous)$$c2018$$dQ1 000079550 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000079550 700__ $$0(orcid)0000-0002-3867-2182$$aBenedicto, D.$$uUniversidad de Zaragoza 000079550 7102_ $$12002$$2647$$aUniversidad de Zaragoza$$bDpto.
