Abstract

A new type of all fiber inline Mach-Zehnder interferometer (MZI) based on single mode-multimode-thin core-multimode optical fiber and cascaded with a fiber Bragg grating (FBG) structure is proposed. Its temperature performance is experimental studied. In our experiments, the sensitivity of this MZI is about 157pm/℃ from 17 to 95°C. When FBG is heated only, the temperature sensitivity of FBG cascaded MZI is 9.83pm/℃. It can be found that the reference spectrum dip wavelength of MIZ can be modulated by cascaded FBG.
