Abstract :
A femtosecond laser trimmed fiber taper as a Mach-Zehnder interferometer in a standard single-mode optical fiber is demonstrated to achieve simultaneous measurement of axial strain and temperature. The experimental results indicate axial strain sensitivities of -1.0 and -1.2 pm/με (blueshift) and temperature sensitivities of 81.3 and 98.8 pm/°C (redshift) at two interference orders of m1 (95) and m2 (90), respectively.
