Paper Abstract

Recently, the bending efficiency of vertical slot waveguide with different structure has been analyzed. However, the interface roughness of the waveguide which have high E-field intensity induces to high scattering loss. In addition, a vertical slot fabrication involves in a very narrow region etching which can cause large roughness in the vertical interfaces. In order to reduce the propagation loss and facilitate the fabrication process, horizontal slot waveguides have been proposed and fabricated, recently. In this paper, we have designed and analyzed total internal reflection (TIR) mirror for using a resonator based on horizontal slot waveguide. Our proposed structure is consisted horizontal slot waveguide of rib type to enlarge contact region with TIR mirror. To analyze Goos-Hänchen shift, we have theoretically calculated length of evanescent field at TIR mirror using 3D-FDTD method. The presented TIR mirror loss analysis can be applied to enhance the efficiency of horizontal slot waveguide resonator which can potentially be used in many silicon based optoelectronic devices.
