Paper Abstract

We report an approach to achieve simultaneous measurement of refractive index and temperature by using a Mach- Zehnder interferometer realized on a tapered single-mode optical fiber with the advantages of low-cost simple fabrication technique. Electrical arc method has been adopted to fabricate the abrupt tapers. The attenuation peak wavelength of the interference with specific order in the transmission spectrum shifts with the changes in the environmental refractive index and temperature. Experiments indicated the corresponding sensitivities of -23.188 nm/RIU (refractive index unit) (blue-shift) and 0.071 nm/°C (red-shift) for the interference orders of 169, respectively.
