摘要
提出了一种分析具有非均匀零色散波长光纤中四波混频 (FWM )的简便方法 ,导出了多段不同零色散波长组成的光纤中和零色散波长连续变化的光纤中四波混频效率的计算公式 .实例计算结果表明 ,光纤中零色散波长分布的不均匀 ,会影响四波混频效率 ,特别是在抽运光和检测光波长间隔较大时 ,影响尤为显著 .
A simplified analyzing method of four wave mixing (FWM) in an optical fiber with nonuniform zero dispersion wavelength has been presented in this paper. The calculation formulas of FWM efficiency has been derived, and the FWM efficiency of some practical examples has been calculated. The results show that the nonuniformity of zero dispersion wavelength in an optical fiber has a remarkable effect on the efficiency of FWM, especially when the interval of wavelength between the pumping light and probe light is large.
