Abstract

We demonstrate the presence of strong longitudinal electric fields (Ez ) in silicon nanowire waveguides through numerical computation. These waveguide fields can be engineered through choice of waveguide geometry to exhibit amplitudes as high as 97% that of the dominant transverse field component. We show even larger longitudinal fields created in free space by a terminated waveguide can become the dominant electric field component, and demonstrate Ez has a large effect on waveguide nonlinearity. We discuss the possibility of controlling the strength and symmetry of Ez using a dual waveguide design, and show that the resulting longitudinal field is sharply peaked beyond the diffraction limit.
