Enhancing the Sensitivity of SMS Fiber Sensors by the Use of High Refractive Index Coatings

Abstract

This paper presents a study on the behavior of single-mode/multimode/single-mode sensors with diamond-like carbon coating of high refractive index. Spectra and response for different values of the external medium refractive index are recorded and analyzed.
