Abstract
We report on an optical fiber Raman temperature Sensor with a backscattering nonlinear mirror. four ports of one 2×2 coupler link the two sensing optical fiber, one incident optical fiber, one output optical fiber respectively and the two sensing fiber make a bunch. On the condition that the quasi-continuous wave input, the 1:1 2×2 coupler forms the backscattering nonlinear mirror, so the signals received by the detector will take four times of what a single sensing optical fiber does. We make up the experimental system and the agreement with the theory is reasonable.
