Abstract
The study of propagation in optical fibres with non-uniform dispersion has recently become a key topic in long haul optical communications. By using combinations of fibres with opposite sign dispersions, it is possible to construct a system which has high local dispersion at any given point, but a low path-average dispersion. This procedure strongly modifies the nonlinear transmission properties of the system compared with one constructed from uniformly low dispersion fibre, because the efficiency with which nonlinear four wave mixing processes are phase matched is substantially reduced[1, 2].
