A strain sensor based on in-line fiber Mach–Zehnder interferometer in twin-core photonic crystal fiber

We experimentally demonstrate a strain sensor realized using a twin-core photonic crystal fiber (PCF). The strain sensor element consists of a 10cm long in-fiber Mach–Zehnder interferometer consisting of twin-core PCF. The output spectra of the sensing element is measured and analyzed under various...

Zusammenfassung:We experimentally demonstrate a strain sensor realized using a twin-core photonic crystal fiber (PCF). The strain sensor element consists of a 10cm 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 −0.31pm/µε is achieved within a range from 0 to 4000µε. The effect of temperature is also analyzed.
