Inelastic Collision and Switching of Coupled Bright Solitons in Optical Fibers

摘要: By constructing the general six-parameter bright two-soliton solution of integrable coupled nonlinear Schr\"odinger equation (Manakov model) using Hirota method, we find that solitons exhibit certain novel inelastic collision properties, which have not been observed in any other $(1+1)$-dimensional soliton system so far. In particular, identify exciting possibility switching between modes by changing phase. However, standard elastic property is regained with specific choices parameters.
