The input pixel size of a polarization-encoded optical shadow-casting logic system is reduced by means of truth-table partitioning. The proposed design algorithm is used to encode the inputs of a three-input, two-output binary full adder. A comparison with alternative designs proves that the technique leads to an improved memory-efficient optical computing unit.

Reversible logic is the emerging field for research in present era. The aim of this paper is to realize different types of combinational circuits like full-adder, full-subtractor, multiplexer and comparator using reversible decoder circuit with minimum quantum cost. Reversible decoder is designed using Fredkin gates with minimum Quantum cost. There are many reversible logic gates like Fredkin Gate, Feynman Gate, Double Feynman Gate, Peres Gate, Seynman Gate and many more. Reversible logic is defined as the logic in which the number output lines are equal to the number of input lines i.e., the n-input and k-output Boolean function F(X1,X2,X3, ...,Xn) (referred to as (n,k) function) is said to be reversible if and only if (i) n is equal to k and (ii) each input pattern is mapped uniquely to output pattern. The gate must run forward and backward that is the inputs can also be retrieved from outputs. When the device obeys these two conditions then the second law of thermo-dynamics guarantees that it dissipates no heat. Fan-out and Feed-back are not allowed in Logical Reversibility. Reversible Logic owns its applications in various fields which include Quantum Computing, Optical Computing, Nano-technology, Computer Graphics, low power VLSI etc. Reversible logic is gaining its own importance in recent years largely due to its property of low power consumption. The comparative study in terms of garbage outputs, Quantum Cost, numbers of gates are also presented. The Circuit has been implemented and simulated using Tannaer tools v15.0 software.

Optical micro-ring resonators (MRRs) element can be used in many applications. This paper we propose a photonics circuit design based on optical tree architecture (OTA) for all-optical elements by using the modified add-drop filter for an all-optical arithmetic logic unit (ALU) aimed for computing applications system. All-optical 2x4 decoder, all-optical comparator, all-optical half adder, all-optical half subtractor, all-optical full adder, all-optical full subtractor and proposed new design all-optical 4x16 decoder were proposed. We have studied the nonlinear effect in the modified add-drop filter system, which is control by injected the nonlinear pulses on top as an input for generated all-optical logic and arithmetic operations simultaneously at the through and drop port of modified add-drop filter. The optical input and control field of the modified add-drop filter circuit can be formed by nonlinear dark and bright pluses. The obtained simulation results have shown that the nonlinear pulse generated by the nonlinear modified add-drop filter can control the output consistency, which is important when the interconnect between each circuit output parts are required. The advantages of the modified add-drop filter are low power, ultra-fast switching, tuneable and high security which is compact size and footprint. It is suitable for the next generation of all-optical small-scale device and all-optical computing system requirements.
