Method of soliton pulses formation

The paper presents the results of numerical modeling field electromagnetic wave propagating in the ring optical resonator connected to optical waveguides. The dependence of the amplitude of the wave field in a ring resonator for different coupling coefficients and frequency at different values of losses in the resonator is given. It is noted the possibility of forming of solitons in a ring resonator in the vicinity of the resonance frequency by the pumping power level which can be much lower the threshold. A new approach to enter soliton pulses in optical path is proposed.
