Abstract

In this work we present the fabrication and characterization of tapered polymer fibers used as fluorescence based sensors with a side-illumination arrangement. The fabrication method consists of a travelling-heater that gives a tight control of the tapered fibers parameters, namely the taper waist and the profile of the transition length between the unaltered fiber and the taper waist. Furthermore, a different approach for using fluorophores in fluorescence based sensors has been developed. With our method, we can locally introduce a fluorescent dye inside the taper region, which could lead to the generation of cuasi-distributed sensors for lengths of hundred of meters.
