A complete all-optical-processing polarization-based binary-logic system, by which any logic gate or processor could be implemented, was proposed. Following the new polarization-based representation, a new Orthoparallel processing technique that allows for the creation of all-optical-processing gates that produce a unique output once in a truth table, was developed. This representation allows for the implementation of all basic 16 logic gates, including the NAND and NOR gates that can be used independently to represent any Boolean expression or function. In addition, the concept of a generalized gate is presented, which opens the door for reconfigurable optical processors and programmable optical logic gates. The gates can be cascaded, where the information is always on the laser beam. The polarization of the beam, and not its intensity, carries the information. The new methodology allows for the creation of multiple-input-multiple-output processors that implement, by itself, any Boolean function, such as specialized or non-specialized microprocessors. The Rail Road (RR) architecture for polarization optical processors (POP) is presented. All the control inputs are applied simultaneously, leading to a single time lag, which leads to a very-fast and glitch-immune POP. A simple and easy-to-follow step-by-step design algorithm is provided for the POP, and design reduction methodologies are discussed. The algorithm lends itself systematically to software programming and computer-assisted design. A completely passive optical switch was also proposed. The switch is used to design completely passive optical gates, including the NAND gate, with their operational speeds only bound by the input beams prorogation delay. The design is used to demonstrate various circuits including the RS latch. Experimental data is reported for the NAND and the Universal gate operating with different functionality. A minute error is recorded in different cases, which can be easily eliminated by a more dedicated manufacturing process. Finally, some field applications are discussed and a comparison between all proposed systems and the current semiconductor devices is conducted based on multiple factors, including, speed, lag, and heat generation.
