对模间四波混频(FWM)进行了理论和实验研究。在分析了相位匹配条件作为有效的四波混频的基本条件之后，我们给出了各模的传输特性，如差模延迟和色散对产生的闲置光功率的影响。通过对联运四波混频的实验测量，验证了理论分析。我们得出的结论是，高效的宽带四波混频只能针对一种特定的四波混频工艺实现，并且在所有相互作用的光纤模式中需要非常接近的色散值。
We present a theoretical and experimental investigation of inter-modal four-wave mixing (FWM). After analyzing the phase-matching condition as the fundamental condition for efficient FWM, we show the impact of the individual mode's propagation characteristics, such as differential mode delay and chromatic dispersion on the power of the generated idler. We verify the theoretical analysis with experimental measurements of intermodal FWM. We conclude that efficient broadband intermodal FWM can only be achieved for one specific FWM process and requires very close values of chromatic dispersion in all interacting fiber modes.
