摘要
研究了色散位移光纤零色散区域附近的四波混频特性,讨论了当零色散波长彼此不同的多段光纤连接起来后对四波混频效率的影响。理论计算结果表明,在信号光和抽运光波长间隔较小的区域,各光纤对四波混频过程都有贡献,且互相调制,并出现增益现象,有着很复杂的效率图。
Abstract
The four-wave mixing behavior near the zero-dispersion region of the dispersion-shifted fiber is theoretically studied and the case in which several dispersion-shifted fibers with different zero-dispersion wavelengths are combined together for four-wave mixing is considered. The results show that the four-wave mixing in all the dispersion-shifted fibers contributes to the total conversion efficiency, the parametric gain is apparent and the three-dimension efficiency line is very complicated when the signal-pump wavelength separation is small enough.
