Classical forces on solitons in finite and infinite nonlinear planar waveguides
Classical forces on solitons in finite and infinite nonlinear planar waveguides
Abstract Conservation equations for the mass, linear momentum, and energy densities of solitons propagating in finite, infinite, and periodic nonlinear planar waveguides and governed by the nonlinear Schrödinger equation are derived. These conservation equations are used to determine classical force densities that are compared with those derived by drawing a …
