【摘要】 本文利用基于双线性算符的广田法给出了带有有限带宽光增益和损耗项的非线性Ｓｃｈｒｏｄｉｎｇｅｒ方程的孤立波解，结果表明，通过适当地选取光增益谱和光纤色散参数，孤子自频移和三阶色散能够完全得到补偿，这对实现超高码率（＞１００Ｇｂｉｔ／ｓ）的光传输系统具有重要的意义。更多还原

【Abstract】 This paper gives the solitary waves solution of the extended nonlinear Schrodinger equation with the bandwidth-limited optical gain and loss terms by use of Hirota method based on the bilinear operator. The result shows that by the proper choice of the optical gain spectrum and the dispersion parameters of the fiber both the soliton self-frequency shift and third-order dispersion can be completely compensated, It is very significant for achieving ultrahigh bit rate (>100 Gbit/s)optical transmission systems.更多还原
