Abstract
Two different silicon slot waveguide configurations are thoroughly analyzed to achieve the optimum nonlinear
performance. In the slot region, a complementary metal–oxide–semiconductor-compatible material made by
silicon nanocrystals embedded in silica SiO<sub>2</sub> has
been considered. This material has demonstrated very promising characteristics for nonlinear applications. The
optimum parameters for each configuration are first designed to achieve maximum field confinement in the slot
region. Minimum effective areas around 0.1 µm<sup>2</sup> are
obtained for both configurations. The influence on the field confinement of the variation of the refractive index in
the slot region and the variation of the sidewall angle is investigated. In the former, it is shown that the
variation of the refractive index in the slot region has a small effect on both slot waveguide configurations.
However, the influence of the sidewall angle on the field confinement depends on the configuration chosen.
