Design of XOR/NOT gate and power-phase comparator by gold air-gap composition in silicon wiring technology

The large differences between the refractive index of Si and SiO2 in the SOI composite (silicon on insulator) and, as a result, its high ability to trap lasers, have led to the construction of valuable optical equipment in recent years. In this paper, with a new idea, by adding two reciprocating golden walls and a transverse air gap, the SOI structure is developed in such a way that equipment made with the new method, such as XOR and NOT gates and power-phase comparators, have a dreamy speed and a super small size. This structure is only compatible with linear polarization so that the axis of polarization, which is the direction of the electric field, is parallel to the gold plates. In the multifunctional structure presented in this paper, if the inputs are uniform plane waves, the output will be uniform plane wave with high accuracy and that the inputs can be phase or power while the output is only power. Simulation in this paper is done using finite-difference-time-domain method.
