| Abstract: | We have derived the nonlinear wave equations for an envelope of an electroma-gnetic wave in an axially nonuniform dielectric waveguide by use of the recently developedreductive perturation technique. Concrete example is given for a singlemode optical fiberwhere the coefficient of resultant nonlinear equations with higher- order dispersion anddissipation are given in terms of proportions of the eigenfunction of the guided wave aswell as the material nonlinearity and dispersion.Wave equations are also given to describeferetosecond pulse propagation in slowly varying dielectric waveguides |
