Abstract :
In this paper, the relationship between the nonlinear effect and the cross-section of the waveguide is studied by computing the modal effective area. And the structure of both wire and slot waveguide are optimized to enhance the nonlinear effect in waveguide core and cover. It is found out that the slot waveguide is a better candidate to take advantage of the nonlinear effect in the cover material and the optimized slot thickness is about 20nm to get the strongest nonlinear gain in slot.
