SUMMARY

Anomalous dispersion is crucial in Four Wave Mixing (FWM) as it enhances the interaction strength, leading to more efficient signal generation and amplification. The use of High Nonlinear Fiber (HNLF) is particularly effective in this context, as it facilitates the necessary conditions for FWM to occur. Research indicates that operating in the anomalous dispersion regime maximizes the nonlinear effects essential for effective FWM applications. Relevant literature on this topic may be limited, but understanding these principles is vital for advancements in fiber optics technology.

Hello everyone
I need to know why is it so important to use anomalous dispersion in FWM which four wave mixing and is there any experiment using HNLF high nonlinear fiber ??
Any papers about that I tried. To look but nothing
 
Science news on Phys.org
Would be nice if you explained your abbreviations.
I suppose in Four Wave Mixing (?), simply the interaction is strongest in the region of anomalous dispersion.

Yes FWM is four wave mixing , so any thoughts ?
