Abstract
While gold wire grids have been used to polarize infrared wavelengths for over a hundred years, they are not appropriate for shorter wavelengths due to their large period. With embodiments of the present invention, grids with periods a few tens of nanometers can be fabricated. Among other things, such grids can be used to polarize visible and even ultraviolet light. As a result, such wire grid polarizers have a wide variety of applications and uses, such as, e.g., in the fabrication of semiconductors, nanolithography, and more.
