Abstract :
The control of the group velocity dispersion (GVD) is of great concern in the design of photonic devices and may be obtained controlling the waveguide components of the GVD. Under high optical field intensity the dispersive properties of the waveguides are different from the linear state and a nonlinear model of the guide must be considered. A rib waveguide has been investigated and a finite element procedure together with a second-order perturbation technique have been used to calculate the waveguide dispersion and to compare the results in linear and nonlinear states
