摘要: | A numerical method is proposed to solve the coupled equations between the soliton and bidirectional Raman pump waves. The pump depletion due to the soliton is obtained without using the constant depletion approximation. With this method, the soliton propagation in a Raman-pumped fiber can be solved accurately. It is found that the constant depletion approximation is valid at a small depletion rate, which requires low soliton power (or long pulsewidth), small material loss, and a short-pump period. In a periodically Raman-pumped fiber, there exists a stable signal energy, which is very sensitive to the pump intensity. We have also studied the stability of the soliton propagation with nonconstant pump depletion. It is found that the stability predicted by nonconstant depletion (NCD) and constant depletion assumption (CDA) are generally different. |
