In this paper, the axis-aligned single mode- four mode- single mode (SFS) fiber structure filter is proposed to be an all-optical temporal differentiator. It's shown that differentiators with different orders can be achieved by adjusting the parameters of the axis-aligned SFS fiber structure filter. All-optical temporal differentiators with orders of 0.375, 0.77 and 1 are obtained by using the axis-aligned SFS fiber structure filter, of which processing errors are 8.08%, 2.81%, 0.74%, respectively. The proposed design provides an easy and competitive way for the realization of the all-optical temporal differentiator.
