Abstract

Si/Chalcogenide glass - hybrid slot waveguide designs are theoretically investigated to facilitate efficient degenerate four wave mixing. The TE-field of the mode concentrates inside the infiltrated slot leading to a nonlinear figure of merit >1. A periodic refractive index change is introduced to create a photonic band gap with associated negative dispersion in the second band. This negative dispersion compensates for the usual positive dispersion from waveguide and materials so that phase matching (group velocity dispersion = 0) can be achieved. Changing the periodicity of the index variation the phase matching frequency can be tuned across the whole near infrared allowing a flexible design of the hybrid photonic components.
