Tema(s): Recursos en línea: Resumen: An approach to achieve simultaneous measurement of refractive index and temperature is proposed by using a Mach-Zehnder interferometer realized on tapered single-mode optical fiber. The attenuation peak wavelength of the interference with specific order in the transmission spectrum shifts with changes in the environmental refractive index and temperature. By utilizing S -band and C/L -band light sources, simultaneous discrimination of refractive index and temperature with the tapered fiber Mach-Zehnder interferometer is demonstrated with the corresponding sensitivities of -23.188 nm/RIU (refractive index unit)and 0.071 nm/ °C, and -26.087 nm/RIU (blueshift)and 0.077 nm/°C (redshift)for the interference orders of 169 and 144, respectively. © 2009 American Institute of Physics.
