  • Passive all optical polarization switch and logic devices utilizing the same
    Patent number: 8331002
    Abstract: A passive all optical polarization switch and apparatus and methods for implementing logical operations using the switch is provided. The switch converts a first polarized beam having a polarization angle equals to or nearly equals to ±45 degrees into a beam equal to or nearly equal to the vertical component of the first polarized beam. The switch converts a second polarized beam having a polarization angle equals to or nearly equals to ±45 degrees into a beam equal to or nearly equal to the horizontal component of the second polarized beam. The switch combines the vertical component of the first polarized beam and the horizontal component of the second polarized beam to produce an output polarized beam. The switch is used to implement all optical polarization logic gates.
