All-optical first-order temporal differentiator using a mechanically-induced long-period fiber grating (MI-LPFG) in a small diameter fiber is demonstrated. The coupling intensity of the grating can be enhanced by changing the pressure applied on the fiber. The experimental results show that the transfer function of the MI-LPFG in a small diameter fiber is a high precision first-order temporal differentiator.
