Va. Makarov et Kp. Petrov, SOLITONS AND SOLITARY WAVES IN A NONLINEA R GYROTROPIC MEDIUM WITH FREQUENCY DISPERSION, Kvantovaa elektronika, 20(10), 1993, pp. 1011-1015
Previously unknown accurate solutions have been found to the system of
equations for slowly varying amplitudes of circularly polarized compo
nents of optical field. The solutions describe the solitary waves of n
ontrivial ellipticity. The ranges of parameter values are obtained for
an isotropic nonlinear gyrotropic medium, in which various types of t
he obtained solutions are possible. Stability of the solutions has bee
n numerically analyzed.
