We review our recent advances on the experimental realization and application of ultrafast all-optical temporal differentiators. Differentiation has been obtained via all-fiber filtering based on a simple diffraction gratingassisted mode coupler (uniform long-period fiber grating) that performs full energy conversion at the optical carrier frequency. Due to its high bandwidth, this device allows processing of arbitrary optical signals with subpicosecond temporal features (down to 180-fs with the specific realizations shown here). Ultrafast all-optical differentiators are of interest for a wide range of applications, including ultrahigh-bit-rate optical communications, ultrafast optical computing and information processing, optical pulse shaping and metrology of ultrafast optical events.

Abstract

We review our recent advances on the experimental realization and application of ultrafast all-optical temporal differentiators. Differentiation has been obtained via all-fiber filtering based on a simple diffraction gratingassisted mode coupler (uniform long-period fiber grating) that performs full energy conversion at the optical carrier frequency. Due to its high bandwidth, this device allows processing of arbitrary optical signals with subpicosecond temporal features (down to 180-fs with the specific realizations shown here). Ultrafast all-optical differentiators are of interest for a wide range of applications, including ultrahigh-bit-rate optical communications, ultrafast optical computing and information processing, optical pulse shaping and metrology of ultrafast optical events.
