Abstract: We experimentally demonstrate a strain sensor realized using a twin-core photonic crystal fiber (PCF). The strain sensor element consists of a 10 cm long in-fiber Mach-Zehnder interferometer consisting of twin-core PCF. The output spectra of the sensing element is measured and analyzed under various strain levels. The sensitivity of the strain measurement of -0.31 pm/με is achieved within a range from 0 to 4000 με. The effect of temperature is also analyzed.
