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