Abstract :
An optical fiber humidity sensor composed of a chitosan-coated, waist-enlarged bitaper-based Michelson interferometer (WEBMI) is presented. The achieved sensitivity is further enhanced by more than 5 times, from 26 pm/%RH to 135 pm/%RH, by reducing the fiber cladding thickness and oxidizing the chitosan film.
