We propose and demonstrate a directed optical logic circuit that can perform the XOR and XNOR logic operations consisting of two cascaded microring resonators, i.e., an upper waveguide and an under ...

In this brief, a novel XOR/XNOR-function logic gate with two inputs, two enable inputs and one output is proposed and designed in Quantum-dot Cellular Automata (QCA) nanotechnology. In order to ...
