摘要
对Katok和Shchepkina合成方法的改进(见technology . and Constr.)。在选举。没有装备。1, p.28-33, 1999)的单模光纤的建议。利用给定的传播模式的相速度和群速度值,该方法在光纤的横截面上恢复折射率的轮廓。结果表明,这些值完全决定了折射率的变化,从而决定了光纤中速度色散的变化。得到并讨论了具有放大通带的单模光纤。
A modification of the synthesis method of Katok and Shchepkina (see Tech. and Constr. in Elect. Equip., no.1, p.28-33, 1999) for single-mode optic fibres is proposed. Using given values of the phase and group velocities of a propagating mode, the method restores a profile of the refractive index in the cross section of the fiber. It is shown, that these values determine completely the changes of the refraction index, and, therefore, the variance of the velocity dispersion in the optical fiber. Single-mode fibers with an enlarged passband are obtained and discussed.
