Abstract: By using the model of equivalent dipole of active molecules, and on the basis of the method of dyadic Green's functions and the expansions of the fields in terms of vector cylindrical wave functions, the analysis of the inelastic scattering by active molecules embedded in a single mode optical fiber is given. The analytical expressions and the numerical results of the scattering coefficients for the inelastically scattered guided HEn modes are obtained. The problem of coupling between the elastic even(odd) and inelastic odd (even) HEn modes is considered at the same time.
