Abstract

This paper presents the analytical and numerical results of an investigation the dynamics of coupled spatial solitons where the solitons reside, in general, in different planar waveguides. The solitons have the same frequency and polarisation and the waveguides are identical. A very important aspect of the theory, however, is that the nonlinear coupling does not ignore any cross-terms. The ommission of many coupling terms, which characterises nearly all published calculations on nonlinear couplers, cannot always be logically justified and this point has attracted some recent attention^1,2.
