Abstract

As technologies for dispersion compensation in optical fiber communication systems becoming matured, one of the impairments on future high bit-rate systems no doubt is due to the optical fiber dispersion slope (DS). The performance of future high-speed systems rely on the capability of compensators to map the total transmission DS. Nonlinear-chirped fiber Bragg gratings (NCFBGs) which possess quadratic delay, have been demonstrated for DS compensation.^1,2 The quadratic chirp in the FBGs can be inscribed permanently during fabrication³ or induced by imparting either mechanical or temperature effect to transform it into a NCFBG.^4,5
