Abstract

The fabrication and characterization of long-period gratings (LPGs) in fiber tapers is presented alongside supporting theory. The devices possess a high sensitivity to the index of aqueous solutions due to an observed spectral bifurcation effect, yielding a limiting index resolution of ±8.5×10-5 for solutions with an index in the range 1.330-1.335.

Uncontrolled Keywords: bifurcation, diffraction gratings, fibre optic sensors, optical fibre fabrication, optical fibre testing, refractive index measurement, temperature measurement, temperature sensors, fiber tapers, long-period gratings, spectral bifurcation effect, tapered LPG, long-period fiber gratings, optical fiber devices, optical fiber tapers
