| Summary: | In this paper, a novel strain sensor is proposed and demonstrated by employing a modified photonic crystal fiber (PCF)-based Mach–Zehnder interferometer, in which a collapsed region is introduced at the middle point of the PCF to improve the extinction ratio. Experimental results show that this proposed structure has a high sensitivity of 11.22 <formula formulatype="inline"><tex Notation="TeX">$\hbox{dB/m}\varepsilon$</tex></formula> over a range of 1.28 <formula formulatype="inline"><tex Notation="TeX">$\hbox{m}\varepsilon$</tex></formula> and high-temperature stability. |
