Click For Summary
Anomalous dispersion is crucial in four-wave mixing (FWM) as it enhances the interaction between light waves, leading to more efficient nonlinear processes. The discussion highlights the need for experimental evidence using high nonlinear fibers (HNLF) to better understand this phenomenon. Participants express difficulty in finding relevant research papers on the topic, indicating a gap in accessible information. Clarification of abbreviations and terms related to FWM is also requested to facilitate understanding. Overall, the importance of anomalous dispersion in FWM and the need for further experimental studies are emphasized.

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
 
Physics 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 ?
 

Thread 'Is this a coincidence?... (distances between planets)'

I'm not a student or graduate in Astrophysics.. Wish i were though... I was playing with distances between planets... I found that Mars, Ceres, Jupiter and Saturn have somthing in common... They are in a kind of ratio with another.. They all got a difference about 1,84 to 1,88x the distance from the previous planet, sub-planet. On average 1,845x. I thought this can be coincidential. So i took the big moons of Jupiter and Saturn to do the same thing jupiter; Io, Europa and Ganymede have a...
