چکیده
|
We investigate the temperature- dependences of the brillouin frequency shift in three different kind of single-mode fibers using a heterodyne method for sensing temperature. positive dependences coefficients of 0.77, 0.56 and 1.45mhz/0c are demonstrated for 25 km long single-mode fiber, 10 km long non-zero dispersion shifted fiber and 100 m photonic crystal fiber, respectively. the results indicate that microstructure fibers with a partially ge- doped small core have great potential for fiber brillouin distributed sensing.
