摘要
理论分析了基于四波混频(FWM)实现ROF(光载射频系统)全光波长变换。在分析基于高非线性光纤中FWM效应实现全光波长转换的基础上,指出影响转换效率的主要因素,讨论了提高转换效率的几种方法,采用提高非线性系数、光纤长度、调整泵浦光的功率以及信号光和泵浦光偏振方向之间的关系可以有效地提高基于FWM的波长变换效率,从而为在ROF系统中高效实现波长变换技术提供了依据。同时通过仿真实验,验证了已有的理论分析。
The all-optical wavelength conversion based on FWM in radio over fiber（ROF） system is theoretically analyzed. Based on the analysis of the all-optical wavelength conversion in high-nonlinear fiber, main factors related to the conversion efficiency are presented. Methods to increase the conversion efficiency are discussed. With the longer high-nonlinear fiber, the higher nonlinear coefficient, the appropriate power of the pump, the appropriate polarization between the signal and the bump, and high efficiency to implement the wavelength conversion can be achieved. The theoretical analysis is verified by the simulation results.
