Paper Abstract

A simple temperature sensor based on a bent singlemode–multimode–singlemode (SMS) fiber structure fastened on a polymer base plate is proposed and experimentally investigated. The surrounding refractive index (RI) is higher than that of the silica fiber and RI changes with temperature will not lead to wavelength shift. This SMS fiber structure utilizes changing of temperature to control the curvature of SMS fiber which is induced by expanding of polymer base plate. The shifts of central wavelength are measured at temperature range from 59 to 82 °C. The proposed temperature sensor offers sensitivity of 3.9 nm/°C, which is significantly higher than that of a normal straight SMS structure or a grating-based fiber structure.
