In this project, the feasibility of a new type of fiber-optic humidity sensor based on a Mach-Zehnder Interferometer (MZI) in a normal single-mode fiber (SMF) with waist-enlarged fusion bitapers is explored. A special coating of chitosan is adhered to the cladding mode of the optical fiber, and this...
