We present an all-optical temperature sensor device made of an MXene VC integrated runway-type microfiber knot resonator (MKR) for the first time. MXene VC is coated on the surface of the microfiber by optical deposition. The experimental results show that the normalized temperature sensing efficiency is ∼1.65 dB °C mm. The high sensing efficiency of the temperature sensor we proposed benefits from the efficient coupling of the highly photothermal material MXene and the runway-type resonator structure, which provides a better idea for the preparation of all-fiber sensor devices.
我们首次展示了一种由MXene VC集成跑道型微光纤结谐振器（MKR）制成的全光温度传感器装置。通过光沉积将MXene VC涂覆在微光纤表面。实验结果表明，归一化温度传感效率约为1.65 dB/°C·mm。我们提出的温度传感器的高传感效率得益于高光热材料MXene与跑道型谐振器结构的有效耦合，这为全光纤传感器装置的制备提供了更好的思路。
