ABSTRACT:
A two-dimensional photonic crystal slab apparatus having a waveguiding capability is provided. Noncircular holes are introduced to replace the circular holes in the two-dimensional lattice of the photonic crystal to provide waveguiding capability. Waveguide bends and splitter using noncircular holes with high transmittances are described for symmetry planes of the two dimensional lattice structure.
