Paper Abstract

The optical properties of a nanoscale silicon slot-waveguide has been rigorously studied by using a full vectorial H-field finite element method (VFEM) based approach and presented in this paper. The variations of effective indices, effective areas, power densities in the slot-region and the confinement factors of the slot waveguide, with both horizontal and vertical slots, are thoroughly investigated for quasi-TM and TE modes. The full vectorial magnetic and electric field profiles, and Poynting vector (Sz) are also presented.
