Mutual compensation of the higher-order nonlinearity and the third-order dispersion

摘要: Abstract We obtain the exact bright and dark solitary wave solutions of nonlinear Schrodinger equation (NLSE) with higher-order nonlinearity third-order dispersion without any specified conditions, analyze features solutions. The results show that can mutually compensate for a soliton just as usual self-phase modulation (SPM) group-velocity (GVD) in NLSE; whether or exists monomode optical fiber is determined by sign instead group velocity dispersion; peak intensity proportional to ratio nonlinearity; depends on width η, so no bound N -soliton states exist.
