Abstract

A fiber-optic interferometric temperature sensor is fabricated using a hollow optical fiber with 8 um air hole. Thisinterferometric sensor for measuring temperature consists of 13 m long hollow optical fiber whose one end is attachedto the single mode fiber and the other end is cleaved. After the sensor is put in a furnace, the phase change of the sensoroC to 100oC. The phase change of thefiber sensor is proportional to the change of temperature and the relationship between the change of phase and temperatureis approximately linear. The sensitivity of this sensor is 2.7 radians/oC.
