Relation between refractive index and model equation

  1. Aug 25, 2013 #1
    Fact: The refractive index depends on the medium.
    Also, in general, to study the pulse propagation in a medium, there is a governing model equation (e.g. Non linear Schrodinger equation).

    My question is: Will there be any relation between the model equation and the refractive index? Why?

    Thanks and Regards,

    What does refractive index tell you? i.e. what is it?
    Can you extract that same information from the pulse-propagation study using the governing model equation?
