In this article, half-adder and full-adder gates are implemented by using the structure of photonic crystals and the results are expressed. The effects of structural parameters such as refractive index and radius of rods on the width of the TE/TM mode diagram have been investigated and optimal values for the refractive index and dimensions have been selected. In the following, the effects of plasmonic/graphene structures on logic gate performance have been studied. According to the results obtained in the half-adder mode, the best refractive index for the rods was n = 4 and the best refractive index for the dielectric was n 0 = 0.85. Also, by creating the plasmonic effect of copper rods, the best refractive index for dielectric background was n 0 = 1.8. It should be noted that finally, an improved structure was presented. The proposed plasmonic structure permits TM mode to propagate in it and therefore, it is possible to minimize the size of structure to the nanoscale.

基于光子晶体研究半加器和全加器的等离子体效应

本文利用光子晶体的结构实现了半加器和全加器门，并给出了结果。研究了诸如折射率和杆半径等结构参数对 TE/TM 模式图宽度的影响，并选择了折射率和尺寸的最佳值。下面，研究了等离子体/石墨烯结构对逻辑门性能的影响。根据在半加器模式下获得的结果，棒的最佳折射率为 n = 4，电介质的最佳折射率为 n 0 = 0.85。此外，通过创建铜棒的等离子体效应，介电背景的最佳折射率为 n 0 = 1.8。应该指出的是，最后提出了一种改进的结构。
