%X The polarization-temperature characteristic of single-mode(SM)fiber coupler was investigated theoretically and experimentally.An analytic expression shows that the factors affecting the extinction ratio(ER)of the output light of SM fiber coupler include the extinction ratio of the input light and the mode-coupling ratio of the fibers is derived.Then a series of experiments on measuring the extinction ratio of the output light by changing temperature rapidly and using several light sources with different deg...
