摘要
利用含时 Ｈａｒｔｒｅｅ近似法得到光孤子在含光纤损耗、双光子吸收、三阶色散效应的光纤放大器中传输时的量子非线性薛定谔方程，在一定条件下，有量子态的孤子解，并由此方程讨论了经典和量子效应对孤子在光纤放大器中传输时的影响，由此进一步发现，光场算符的量子力学平均值是一系列修正的经典孤于的叠加．
Propagation of optical solitons in fiber amplifiers is discussed by considering a model that includes loss of fiber, two-photon absorption, third-order dispersion effect. We use the time-dependent Hartree approximation to obtain solutions to a quantitative high-order nonlinear Schrodinger equation (NLS), It describes optical pulses propagating in fibers amplifier, under certain conditions soliton solutions exists, the solution for influence of soliton propagation as well as classical and quantum effects are discussed in detail. Further we find that mean value of the field in fiber is the superposition of a series of classical solitons with corrections.
