Abstract
An optical polarizer includes a supporting member and a polarizing film supported by the supporting member. The polarizing film includes at least one layer of a carbon nanotube film, and the carbon nanotubes in a given carbon nanotube film are aligned in the same direction therein. A method for fabricating the optical polarizer includes the steps of: (a) providing a supporting member; (b) providing at least one layer of a carbon nanotube film, the carbon nanotubes in a given carbon nanotube film aligned along the same direction; and (c) adhering a given carbon nanotube film to the supporting member to form the optical polarizer.
