Optical solitons in the parabolic law media with high-order dispersion

The transmission equation of ultrashort optical pulse in the high-order dispersion media with the parabolic law (cubic-quintic) nonlinearity has been studied with the help of the subsidiary ordinary differential equation expansion method. As a result, the optical solitons and triangular periodic solutions are obtained, and the conditions for exact solutions to exist are also given. (C) 2014 Elsevier GmbH. All rights reserved.
