Propose, Analysis and Simulation of an All Optical Full Adder Based on Plasmonic Waves using Metal-Insulator-Metal Waveguide Structure

This paper proposes a full adder with minimum power consumption and low loss with a central frequency of 1550nm using plasmonic Metal-Insulator-Metal (MIM) waveguide structure and rectangular cavity resonator. This full adder operates based on XOR and an‎d logic gates. In this full adder, the resonant wave composition of the first and second modes has been used and we have obtained a high transmission coefficient in the states in which the output must be active. This full adder uses the an‎d and XOR logic gates to be designed with three inputs, which results in the design of a full adder with lower complexity, lower cost and fewer losses than Other full adders in which an‎d and XOR logic gates are combined to be designed with two inputs. The related simulations were performed by FDTD. The obtained results presented a performance similar to the predicted models, while considering approximations with theoretical relations.
