Claim Text:
1. A three dimensional polarization beam splitter (3D-PBS) based on two 2D photonic crystal slabs, wherein said 3D-PBS based on two 2D photonic crystal slabs comprising: a 2D photonic crystal slab positioned at the top part of the 3D-PBS, a 2D photonic crystal slab positioned at the bottom part of the 3D-PBS and perpendicular to said top 2D photonic crystal slab, and an input coupling dielectric block; a P polarization wave output waveguide positioned in said top 2D photonic crystal slab; an S polarization wave output waveguide positioned in said bottom 2D photonic crystal slab; said output port of the P polarization wave output waveguide and the output port of the S polarization wave output waveguide are apart from each other in 3D space; and said two photonic crystal slabs consisting of a background dielectric material and dielectric rods.
