Abstract
The present application discloses a Transverse Electric (TE) polarizer. The TE polarizer includes a silicon-on-insulator substrate having a silicon dioxide layer. The TE polarizer further includes a waveguide embedded in the silicon dioxide layer. Additionally, the TE polarizer includes a plate structure embedded in the silicon dioxide layer substantially in parallel to the waveguide with a gap distance. In an embodiment, the plate structure induces an extra transmission loss to a Transverse Magnetic (TM) mode in a light wave traveling through the waveguide.
