Abstract

Temperature and refractive index are two important parameters for many fields, where their accurate measurement is crucial. This review discusses the development of refractive index and temperature dual-parameter fiber sensors based on different interferometric structures in recent years, such as the Mach–Zehnder, Michelson or Fabry–Perot interferometers, which are composited by the grating reflectors, and multi-separated-region based on thin film layers and special structures. The working principle and performance of different types of sensors are analyzed. This review can provide the technical references for the development of novel dual-parameter sensors with practical potential and high performance.
