Abstract
A wire grid polarizer (WGP) can include an array of support-ribs on a substrate. Sides of the support-ribs can be inclined to one side. A wire can be applied on an upper-side and distal end of each support-rib, each wire being separate from wires on adjacent support-ribs. The WGP can be made with reduced or no etching.
Claims20
A wire grid polarizer (WGP) comprising:
- an array of support ribs on a substrate, each support rib having a parabolic cross-sectional shape at a distal end farthest from the substrate;
- a stack of upper ribs on the distal end of each of the support ribs, the stack including three upper ribs, each upper rib having a parabolic cross-sectional shape at a distal end farthest from the substrate, each upper rib extending down sides of an adjacent support rib or upper rib closer to the substrate;
- and
- each upper rib in the stack separate from upper ribs on adjacent support ribs.

A wire grid polarizer (WGP) comprising:
- an array of support ribs on a substrate, each support rib having a curved cross-sectional shape at a distal end farthest from the substrate;
- a stack of upper ribs on the distal end of each of the support ribs, the stack including two upper ribs, each upper rib having a curved cross-sectional shape at a distal end farthest from the substrate, each upper rib extending down sides of an adjacent support rib or upper rib closer to the substrate;
- the stack of upper ribs includes a cap and a wire;
- and
- the cap is transparent and the wire is reflective across the ultraviolet spectrum, across the visible spectrum, across the infrared spectrum, or combinations thereof.
