This paper proposes a compact fiber-optic temperature sensor based on RIL functionalized SHMOFs and investigates the transmission spectral characteristics from experimental and theoretical perspectives. The sensor exhibits ultrahigh sensitivity and wide measurement range, making it a promising candidate for various applications in environmental monitoring, industrial, and agricultural production.
A compact fiber-optic temperature sensor based on refractive index liquid (RIL) functionalized side-hole microstructured optical fibers (SHMOFs) is proposed and experimentally demonstrated. Transmission spectral characteristics of the proposed temperature sensor have been investigated from experimental as well as theoretical perspectives. Due to the resonance coupling between the fundamental core mode and RIL rod modes, multiple resonance dips are present in the transmission spectrum, which could be tuned by adjusting environmental temperature. Experimental results indicate that the highest temperature sensitivity reaches - 13.1 nm/degrees C for a temperature range of 80-100 degrees C. Hence, the SHMOF-based temperature sensor has several desirable merits such as ultrahigh sensitivity, wide measurement range and ease of fabrication, which make it a promising candidate for various applications in environmental monitoring, industrial and agricultural production.
