Relaxation oscillations of solitons
Kuznetsov E. A., Mikhailov A. V.
The relaxation of a perturbed (amplified) optical soliton is analyzed. A nonlinear interference of the soliton and a radiation field leads to oscillations of the soliton amplitude which are damped in a power-law fashion. A new effect is observed: a mutual attraction of solitons as a result of their interaction with a nonsoliton part. © 1994 American Institute of Physics.
