| Abstract | In this paper, a new method for ultrasensitive temperature measurement is proposed and demonstrated. The sensor is based on two cascaded peanut structures to form a Mach Zehnder interferometer (MZI) in single mode fiber, and a cone is formed by repeat discharge in the interference region to enhance the evanescent field on its surface. At the same time, isopropanol with high thermal optical coefficient is filled for effective sensitization. The MZI was placed in a fiber ring cavity for filtering and temperature sensing. The results show that the fiber ring laser (FRL) has a narrower 3 dB band width (similar to 0.15nm) and a high signal-to-noise ratio (SNR) (similar to 50dB). In the temperature range of 20 degrees C to 50 degrees C, the sensitivity reached -285 pm/degrees C The sensor has the advantages of high sensitivity, simple structure and low cost. It is expected to be widely used in ocean temperature measurement. |
