In this study, a
novel tapered optical fiber sensor based on a Mach–Zehnder interferometer (MZI)
for refractive index measurement is proposed. Our sensor is constructed with
two up-tapers symmetrically placed in a down-taper single mode fiber. Although
its waist diameter is as thick as 55 μm, the sensor can measure the refractive
index. Simulation results demonstrate RI sensitivities of -94 nm/RIU and -125
nm/RIU at the lower and higher wavelength of the spectrum. The sensor is
extremely robust, it can be easily manufactured and it can be used not only for
RI but also for simultaneous strain and temperature measurements.
