A method to fabricate bilayer wire grid polarizer (B-WGP) by nanoreplication and metal vapor deposition was proposed for a simpler and a less costlier fabrication method for the reflective polarizer. We fabricated B-WGP composed of UV-replicated 80nm pitch nanograting structure and E-beam evaporated 50㎚ thick aluminium layer. To examine the performance of the fabricated B-WGP structure, the transmission spectra of TE- and TM- polarized light, and the extinction ratio spectra were measured and compared with the simulated spectra.
