Influence of coupling and intermodal dispersion coefficient on pulse splitting in double core optical fibre was investigated by using solutions of normalized coupled nonlinear Schrödinger equations. It was found that if coupling coefficient and intermodal dispersion coefficient was small, and then nonlinearity cannot balance intermodal dispersion effect. Consequently, pulse was distorted. Furthermore, if intermodal dispersion coefficient was large enough, then pulse splitting occurred. Increasing coupling coefficient avoids pulse splitting and the pulse was stable. © Published under licence by IOP Publishing Ltd.
