| 摘 要： | 采用半经典理论，建立了Ｅｒ3+掺杂光纤中孤子的传输放大方程。该方程考虑泵浦激发态吸收，故适用于０．５－１．４９μｍ波长范围的所有泵浦情况。同时，该方程适用于任意折射率分布光纤，任意泵浦和信号光波模式、任意掺杂形状、均匀加宽和非均匀加宽、集总放大和分布放大，为深入研究Ｅｒ3+渗杂光纤孤子放大特性、优化掺杂光纤设计提供了必须的基本分析方程。

| Abstract: | In this paper the amplification equation of solitons propagating in Er3+-doped optical fibers is established by using the semi-classical theory. This equation takes into account of pump excited-state absoption so that it is applicable to the pump wavelength regime of 0.5-1.49μm. This equation is also applicable to the optical fibers with abitrary refrective index profile. abitrary pump and signal optical wave modes, abitrary doping contribution，homogeneous and inhomogeneous broadening and lumped and distributed amplification, which is a necessary elementary analytical equation for a profound research of tiie characteristics of soliton amplification in the Er3+-doped optical fibers and optirnizing its design. |
