| Abstract: | We show analytically that in the presence of cubic and quintic nonlinearities above a certain critical power, multidimensional optical solitary waves could propagate stably in bulk media. To investigate the stability an analytical expression for the solitary-wave fields with an arbitrary transverse dimension is derived through the combined use of Galerkin’s method and self-consistent-field approximation. |
| Keywords: | optical soliton spatial soliton two-dimensionally self-trapped beam cubic-quintic nonlinearity stability analysis |
