Title:Study of light propagation in optical fiber with randomly varying birefringence.

Abstract :

 Polarization Mode Dispersion (PMD) is the main limiting effect of high 
bit rate
transmission in long distance communication. It has its origin in the 
randomly
varying birefringence. A model, called the Manakov PMD equation, has 
been introduced
to study this phenomenon. The particularity of this model is the 
various length
scales appearing in the equation. In this talk, I will explain how a 
limit
theorem can be proved (in the sense of convergence in law). I will give 
numerical
results on the limiting equation and estimations on the impact of the 
PMD.
