Abstract
The invention includes a selectively-absorptive wire grid polarizer (WGP) comprising an array of parallel, elongated rods located over a surface of a transparent substrate with gaps between adjacent rods. Each of the rods can include a reflective wire and two absorptive ribs. The reflective wire can be sandwiched between the two absorptive ribs and the substrate or the two absorptive ribs can be sandwiched between the reflective wire and the substrate. Each of the two absorptive ribs can comprise a different material. Use of multiple absorptive ribs within each rod can increase the effective useful bandwidth of light for selectively absorbing one polarization.
