Abstract

A novel fiber optic multimode interference based refractive index sensor by shining zeroth order Bessel-Gauss beam is reported and investigated. The proposed sensing scheme offers a 9.22 times higher sensitivity and an improved refractive index sensing resolution in the magnitude of around tenth order than the sensor using Gaussian beam.
