摘要：
In this paper, we propose and analyze a versatile structure of electro-optical modulator on a polysilicon rib waveguide. The structure confines both optical field and charge carriers in a micron-size region. The optical field is confined by using a coplanar waveguide (CPW) structure. Software based on the Finite Element Method (FEM), allows a complete analysis of the distribution and penetration of the electric field (E) within the polysilicon rib waveguide. This analysis is validated by the use of Kramers-Kronig dispersion relations.
