Abstract:

Sapphire-derived fiber (SDF) has advantages such as good mechanical properties and high temperature resistance. It has a wide range of potential applications in high temperature and distributed strain sensors. This article briefly introduces basic characteristics of SDF.Based on the research accomplishments of the authors' group in recent years, typical components of SDF are presented, mainly including fiber Bragg grating (FBG), Fabry-Perot (F-P) cavity, long period grating (LPG) and Mach-Zehnder interferometer (M-Z). The principle and fabrication method of these SDF-based sensors are investigated and discussed.

Key words: long period grating sensor, fiber Bragg grating, Fabry-Perot cavity, Mach-Zehnder interferometer, sapphire-derived fiber
