Abstract

Evanescent field interaction in side-polished fibre Bragg gratings (FBG) provides a sensor for measuring refractive indices of liquid analytes and thin films with spectral read-out. The specific advantages of FBG sensors - networking capability, independence of variable signal transmission losses - give the potential to a higher diversity and accuracy of opto-chemical measurements than the measurement of transmission intensities through evanescent field sensitive fibre structures.
