Abstract

Aiming at improving the sensitivity of OFDR distributed optical fiber temperature sensors, this paper introduces the design of a temperature sensor with a new structure. In this design, PDMS/Glycerol is coated on the surface of a SMF as a temperature-sensitive material. Within the temperature range from 30 °C to 150 °C, this sensor exhibits excellent temperature stability and repeatability, with an average relative deviation of only 0.16%, and its performance remains stable during temperature cycles. Furthermore, the temperature sensitivity of the sensor is 18.84 pm/°C, representing an 87% improvement compared to that of SMF.

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
