PROPAGATION OF A SOLITON IN A NONLINEAR WAVE-GUIDE WITH DISSIPATION AND PUMPING

Generation of nonsoliton wave field (radiation) by pumping pulses compensating dissipative damping of a soliton moving in a nonlinear optical waveguide is investigated in the framework of a simple model based on a perturbed nonlinear Schrodinger equation. The stationary level of radiation is found, and a condition providing efficiency of the waveguide, i. e. the number of the radiation light quanta being small in comparison with the number of quanta bound in the soliton, is obtained.
