Abstract
A numerical study of soliton pulse in a triangular coupler is presented. Such a device is modeled by using the coupled nonlinear Schrödinger equations, where the numerical method used is the finite element method known as Galerkin technique with discrete time domain using quadratic line elements. The iterative techniques are used to clarify the element position of the device half-beat length. Such iterative technique use is q scheme method, when q is equal to 0.51 is known as the Crank-Nicolson scheme. Results obtained have shown the potential of using such a device for optical switching in highly speed network with reasonable power budget.
