Subwavelength Grating Structures in Silicon-on-Insulator Waveguides

Figure 6

FDTD simulations of HR SOI facets. (a) Layout used for a typical simulation. The light and dark blue regions are the silicon waveguide core and SiO2 lateral cladding, respectively. (b) Simulated TE field map for a waveguide mode launched at the plane indicated in the figure. (c) TE field map for an external optical fiber mode coupling into the waveguide.
