Why large bandwidth is needed in Four Wave Mixing process?

[eahaidar]

Good Morning
I loved the idea of four wave mixing in an optical fiber and how by satisfying phase matching condition you get a broad bandwidth but I want to know why am I interested in a large bandwidth why do I want to think about even enlarge it more?
Thank you

I'm sorry you are not finding help at the moment. Is there any additional information you can share with us?

So I have a process called four wave mixing which if I want high efficiency in this process I should satisfy the phase matching condition as much as possible and if that happens the range of wavelength where FWM occurs is my bandwidth
I want to know why I want large bandwidth in a physics matter
Why should I care about it ?

Moved from General Physics to Electrical Engineering to see if it gets any nibbles there...
