摘　　要：In this paper,the experiment on an all-optical switching is reported based on a microstructure fiber（MF）- nonlinear optical loop mirror（NOLM）. In the experiment, a 25-meter-long MF（ γ = 36W^-1 km^-1@ 1 550 nm） is used as a nonlinear medium of the nonlinear optical loop mirror and the input signal is generated by a 10 GHz tunable picosecond laser source,with a full-width at half-maximum （FWHM） of 2 ps and centered at 1 550 nm. With the increase of input power,a π nonlinear phase shift is obtained by a 40/60 coupler in the experiment,but the same result can not be found by a 48/52 coupler. Additionally,the switching devices can also be used as an all-optical regeneration.
