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.
