Abstract

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 × 10−2°C.
