Abstract:
1. A TE-polarization splitter based on a photonic crystal waveguide, comprising a waveguide formed in a photonic crystal with a complete photonic bandgap, after the incident wave with any polarization direction is inputted into the polarization splitter via the input port of the photonic crystal waveguide, TE wave is outputted from the output port of the polarization splitter, while the TM wave is reflected from the input port of the polarization splitter, wherein said photonic crystal waveguide is provided with the waveguide-defect dielectric rods, and the defect dielectric rods are four square shaped defect dielectric rods, in which the center of each square shaped dielectric rod coincides with the center of circular shaped dielectric rod which was originally deleted in forming the waveguide.
