A wire grid polarizer (10, 20, 30, 40, 50, 60, 70, 80, 90, 100) comprising an array of parallel, elongated first rib groups (14) disposed over a substrate (11). Each first rib group can comprise a central first transmissive rib (12) and a pair of first wires (13) including a first wire disposed along each side of the first transmissive rib. A first dielectric material (16) can substantially fill first gaps between each rib group and an adjacent rib group. An array of parallel, elongated second wires (15) can be disposed over the rib groups and the first dielectric material. The first wires or the second wires can be absorptive and the other of the first wires or the second wires can be reflective. |
