“…There are several well-known methods for analysis of signal propagation in different dielectric waveguides and optical fibres: analytical [1,2,4,6,8], semi-analytical [2,5,8] and numerical [2,7,8]. In the present work we consider a new aspect of the analytical method for analysing linear and nonlinear polariton waves generated in cylindrical dielectric waveguides or optical fibres.…”

It is shown that a sinusoidal signal wave can transform into a cnoidal (periodic) wave in an optical fibre if the power signal propagates in the fibre core. In this case the signal wave period increases, but the wave profile does not almost change. The signal wave gets the form of kink for the high-power signal. The wave transformation is determined by nonlinear effects in the fibre core. The linear modes of the fibre transform into the nonlinear ones under influence of cubic or higher nonlinear interactions of electromagnetic and polarization waves. These changes are described by the equation with sinusoidal nonlinearity for the polarization wave. The approximate and exact analytical solutions of the nonlinear equation are obtained. PACS
