Abstract
A novel temperature-insensitive strain sensor, based on an in-line
Mach-Zehnder interferometer, is fabricated by concatenating two waist-enlarged fiber
tapers separated by a short piece of photonic crystal fiber. The interference
spectrum of the proposed sensor is analyzed in detail. Experimental results
demonstrate that this sensor has a strain sensitivity of 3.02 pm/με and
maintains the temperature insensitivity feature. The proposed sensor has great
potential in diverse sensing applications due to its advantages, such as its compact
size, low cost, and simple fabrication process.
