Abstract

This paper presents a novel photonic crystal structure for designing all-optical photonic crystal logic gates and functions based on threshold logic concept. The structure offers two- and three-input AND/NAND logic gates as well as three-input majority/minority functions. In this method, the summation of inputs values connects to a threshold detector with varying threshold values in order to achieve different logic gates and functions. Furthermore, the impact of variations in the diameter and position of rods on the performance of the proposed structures has been examined. Simulation results demonstrate the successful operation of the proposed structures even in the presence of 14% variation in rod diameter, indicating that the presented logic gates exhibit minimal sensitivity to process variations. The finite difference time domain method was used to evaluate the performance of the proposed structures with a switching power requirement of is 2.5 W.

基于阈值逻辑的全光光子晶体逻辑门和功能

本文提出了一种基于阈值逻辑概念设计全光光子晶体逻辑门和功能的新型光子晶体结构。该结构提供两个和三个输入and /NAND逻辑门以及三个输入多数/少数功能。在该方法中，输入值的总和连接到具有不同阈值的阈值检测器，以实现不同的逻辑门和功能。此外，还研究了杆的直径和位置变化对所提出结构性能的影响。仿真结果表明，即使存在14%的杆径变化，所提出的结构也能成功运行，这表明所提出的逻辑门对工艺变化的敏感性最小。采用时域有限差分法对开关功率要求为2.5 W的结构进行了性能评价。

期刊介绍： he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered. In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
