Design of terahertz-bandwidth arbitrary-order temporal differentiators based on long-period fiber gratings

We show that long-period fiber grating (LPG) incorporating N-1-π-phase shifts can serve as an Nth order temporal differentiator that operates in transmission. Due to the inherent large bandwidth provided by LPGs, subpicosecond (terahertz-bandwidth) optical signals may be processed with centimeters-length devices. Design parameters for up to fifth-order differentiators are given.

Abstract

We show that long-period fiber grating (LPG) incorporating N-1-π-phase shifts can serve as an Nth order temporal differentiator that operates in transmission. Due to the inherent large bandwidth provided by LPGs, subpicosecond (terahertz-bandwidth) optical signals may be processed with centimeters-length devices. Design parameters for up to fifth-order differentiators are given.
