In this paper, an erbium-doped fiber with an upper cone fiber structure which can realize the interference between the cladding mode and the core mode is presented for temperature sensing in fiber ring laser (FRL). Based on this structure, an efficient and inexpensive Mach Zehnder interferometer (MZI) was designed. High signal-to-noise ratio (≈45dB) is realized, and 3dB bandwidth is less than 0.15nm. In addition, compared with MZIS based on misplaced or taper fiber, it has good optical stability. The FRL sensor has a temperature sensitivity of 301 pm/°C. This kind of MZI has great development value in bridge detection and life and health.
