摘要
We propose and demonstrate parallel structured optical fiber in-line Fabry–Perot interferometers for high temperature sensing. The device consists of three Fabry–Perot cavities in parallel connection, which allows three independent fringe patterns superimposed at its output, and, as a result, a number of dominant fringe peaks/dips appear, thus enabling unambiguous measurement in a large range. The device is featured with compact size, robust structure, and excellent high temperature sustainability, which makes it promising in extreme environment monitoring.
