Paper Abstract

This paper discusses the theoretical and experimental implications of tapering a multimode optical fiber with a view to its use in evanescent-wave absorption-spectroscopy. Good experimental results are obtained, showing the possibility of quadruplicating the absorbance efficiency. This easy and reproducible technique for taper fabrication is suitable for the implementation of both probes for spectroscopy and chemically-assisted fiber optic sensors.
