Taking into consideration the transverse confinement, the dispersion of the linear as well as of the nonlinear part of the refractive index and the nonlinear interaction of the electromagnetic field with the guiding material, the yielding equation for the envelope function of the fundamental mode propagating in a strip waveguide is the generalized nonlinear Schrödinger equation. In contrast to the nonlinear Schrödinger equation, solitons of the generalized nonlinear Schrödinger equation exist in the regimes of negative and positive group dispersion and are asymmetric.
