B-class

I've tagged this article as B-class because it nees cleanup for encyclopedic tone. The current text is a mix of conversational tone, for example starting a sentence with "anyway", and textbook or journal-article tone, mainly in the large amount of equations relative to text. -- The Photon 03:02, 13 April 2007 (UTC)[reply]

Problem with Solition Picture

The picture by Alessio Damato doesn't correspond with the text. The text states that higher frequency components travel faster (spatially) than lower ones in the case of GVD, and the opposite for Kerr nonlinearities. However, the picture shows the opposite. For normal dispersion the index of refraction decreases with wavelength, so the velocity of a wave $v=c_{0}/n$ should be faster for higher frequencies than lower frequencies (as in the text). I have modified the image, and will upload unless anyone can show I am wrong.
