Abstract
To fabricate a waveguide with improved light coupling efficiency utilizing second order nonlinear optical coupling processes, localized thickness variations of at least one waveguide layer are first measured instead of assuming a constant thickness. Such localized thickness variations can change the phase matching condition needed to propagate light in the waveguide, thereby reducing efficiency of a waveguide. The width of the waveguide is then fabricated based on the localized thickness variations in order to achieve a desired modal phase matching condition, for example, by finite element modeling. In doing so, the waveguide can improve light coupling efficiency by compensating for localized thickness variations during the fabrication process.
