Abstract | Apparatus and methods for implementing logical operations using polarization-based logic level representation is provided. An apparatus and method split an input polarized beam into a first beam and a second beam, wherein the first beam and the second beam have an identical or nearly identical relative polarization angle that equals or nearly equals the relative polarization angle of the input polarized beam. The apparatus and method further polarize at a first relative polarization angle the first beam and polarize at a second relative polarization angle the second beam. The ratio of the amplitudes of two perpendicular polarization components of the input polarized beam is one or nearly one and the difference between the first relative polarization angle and the second relative polarization angle is 180 degrees or nearly 180 degrees. Furthermore, the relative polarization angle of the input polarized beam equals or nearly equals either the first relative polarization angle or the second relative polarization angle. |
