Abstract

Nowadays the complete control of fibre properties, such as dispersion, is an indispensable technology. For the nonlinearity, however, possibilities are limited particularly due to the difficulty of creating a nonlinear phase response with sign opposite to the Kerr effect. Promising candidates are interferometric devices, such as modified Mach-Zehnder interferometers proposed for nonlinearity management [1] or nonlinear amplifying loop mirrors (NALM) for nonlinear phase-shift compensation in phase-encoded optical transmission systems [2].
