High-sensitivity, evanescent field refractometric sensor based on a tapered, multimode fiber interference
High-sensitivity, evanescent field refractometric sensor based on a tapered, multimode fiber interference
We propose and experimentally demonstrate an enhanced evanescent field fiber refractometer based on a tapered multimode fiber sandwiched between two single-mode fibers. Experiments show that this fiber sensor offers ultrahigh sensitivity [better than 1900nm/RIU at a refractive index (RI) of 1.44] for RI measurements within the range of 1.33 to 1.44, in agreement with the theoretical predictions. This is the highest value reported to date (to our knowledge) in the literature.

Abstract
We propose and experimentally demonstrate an enhanced evanescent field fiber refractometer based on a tapered multimode fiber sandwiched between two single-mode fibers. Experiments show that this fiber sensor offers ultrahigh sensitivity [better than 1900nm/RIU at a refractive index (RI) of 1.44] for RI measurements within the range of 1.33 to 1.44, in agreement with the theoretical predictions. This is the highest value reported to date (to our knowledge) in the literature.
