According to one exemplary embodiment, an optical polarizer positioned before a light source for use in semiconductor wafer lithography includes an array of aligned nanotubes. The array of aligned nanotubes cause light emitted from the light source and incident on the array of aligned nanotubes to be converted into polarized light for use in the semiconductor wafer lithography. The amount of polarization can be controlled by a voltage source coupled to the array of aligned nanotubes. Chromogenic material of a light filtering layer can vary the wavelength of the polarized light transmitted through the array of aligned nanotubes.
