Polarization encoded all-optical ternary Max gate

An all-optical scheme of polarization encoded ternary (3-valued) MAX logic gate with the help of Terahertz Optical Asymmetric Demultiplexer (TOAD) based fiber interferometric switch is proposed and described. For the ternary data processing in optics, the ternary number (0, 1, 2) can be represented by three discrete polarized state of light. Numerical simulation result (by Mathcad-7.0) confirming described method is given in this paper.
