Plasmonic sensor based on tapered optical fibers and magnetic fluids for measuring magnetic fields

摘要

Highlights ? Use of plasmonic devices to measure magnetic field. ? Use of doubly-deposited uniform-waist tapered fibers as refractometers. ? Use of magnetic fluids as transducers. ? Novel concept, very good results in terms of sensitivity. ? Possibilities of further extension of plasmonic techonology for measurements of physical magnitudes. Abstract
