Paper Abstract

We present a theoretical investigation of the dispersive properties of linearly-chirped fiber Bragg gratings, establishing optimal parameters for the refractive index variation along the fiber length. Employing numerical methods, we show that a 3-cm-long chirped Bragg filter is able to compensate for the dispersion from 100 km of fiber at 1.2 micrometers , recompressing a 20 os Gaussian input pulse from its dispersion-broadened 74.4 ps width back to 20.6 ps. We also prove that a uniform grating profile provides the optimum compression for this input pulse type, confirming recently published claims.
