我们利用多模干涉开发了一种非常简单的高灵敏度光纤温度传感器。所制造的多模干涉结构包括夹在单模光纤之间的大芯多模光纤（MMF）。硅橡胶作为包覆材料涂覆在 MMF 上。这种硅橡胶涂层表现出较大的折射率随温度的变化，可产生低至 1 x 10(-2)℃ 的非常精细的温度分辨率
We have developed a very simple high-sensitivity fiber temperature sensor using multimode interference. The fabricated multimode interference structure comprises a large-core multimode fiber (MMF) sandwiched between single-mode fibers. Silicone rubber is coated onto the MMF as a cladding material. This silicone rubber coating exhibits a large refractive-index change with temperature that produces a very fine temperature resolution as low as 1 x 10(-2)degrees C
