Abstract The nonlinear effect and the diffraction effect on a spatial soliton are isolated by rewriting the nonlinear Schrödinger equation into a form of the linear Schrödinger equation with a nonlinear potential. Numerical results on these effects are obtained for a fundamental spatial soliton, a second‐order spatial soliton, and two coupled solitons in a parallel‐plate waveguide. The effects of waveguide loss are also included.
