Generation of asymptotically stable optical solitons and suppression of the Gordon-Haus effect.

By a proper design of the frequency-dependent gain characteristic of optical amplifiers, the parameters (amplitude eta and velocity kappa) of optical solitons in fibers can be made to approach a desired fixed point in kappa-eta space. The method is effective in controlling the random walk of solitons caused either by initial jitter and/or by amplifier noise (the Gordon-Haus effect) and in overcoming the bit-rate limitation that they provide.
