Abstract
A silicon photonic device includes a silicon-on-insulator substrate, a waveguide, and a plate. The silicon-on-insulator substrate includes a silicon layer and a silicon dioxide layer. The waveguide is disposed on the silicon-on-insulator substrate. The silicon dioxide layer at least partially overlays the waveguide. The plate exhibits metallic characteristics and is at least partially embedded in the silicon dioxide layer of the silicon-on-insulator substrate. The plate is spaced apart from the waveguide and is configured to mitigate transverse magnetic emission propagating through the waveguide.
