title: Ultrafast all-optical Nth-order differentiator based on chirped fiber Bragg gratings.
abstract: In this letter we present a technique for the implementation of Nth-order ultrafast temporal differentiators. This technique is based on two oppositely chirped fiber Bragg gratings in which the grating profile maps the spectral response of the Nth-order differentiator. Examples of 1(st), 2(nd), and 4(th) order differentiators are designed and numerically simulated.
