摘要：

In this paper, a strain insensitive high temperature fiber sensor based on the modal interferometer is proposed. It is composed of a piece of small-core photosensitive fiber (SCPSF) which is spliced between two pieces of single mode fiber (SMF). Compared to other high temperature fiber sensor based on the modal interferometer, the sensor owns the highest temperature sensitivity of 106.64 pm/degrees C from 200 degrees C to 1000 degrees C. The temperature to strain cross sensitivity of the sensor is low and only 0.00675 degrees C/mu epsilon. The reasons for realizing the high temperature sensitivity is also discussed.
