Energy consumption is a primary concern in the computational process of heavy networks like Google, etc., where the key goal is to make them ultra-fast with low heat generation. Optical processing can play an important role in shrinking the heat energy and allow the system to work smoothly but beyond the Boltzmann limit of kTLn2. In the current epoch, optical reversible logic functions are greatly considered as a potential solution for minimizing heat dissipation or information loss and found applications in nanotechnology, logic circuits for biomedical applications, and so on. This work proposed the optical Kerr effect-based multifunctional plasmonic logic device. The Kerr effect provides switching of optical signal across the output ports of the Mach-Zehnder interferometer (MZI) with a high extinctionratio (ER). The intensity of the input signal is defined as different states of input logic. In addition, the presence and absence of an optical signal at output ports are used to set logic ‘1’ and ‘0’, respectively. Finally, four different logic functions including reversible Toffoli gate (TG), half adder (HA), NOR and XOR gate are realized through the proposed device. The device is analyzed through the finite difference time domain method in Opti-FDTD. Further, the analysis of basic elements is done in terms of ER, insertion loss (IL), and transmission efficiency.

基于 MIM 波导的相位调制多功能等离子体逻辑器件

能源消耗是谷歌等重型网络计算过程中的一个主要问题，其关键目标是使它们超快且产生低热量。光学处理可以在收缩热能方面发挥重要作用，使系统能够平稳工作但超出kTLn2的玻尔兹曼极限。在当今时代，光学可逆逻辑功能被广泛认为是最大限度地减少散热或信息损失的潜在解决方案，并在纳米技术、生物医学应用的逻辑电路等方面得到了应用。这项工作提出了基于光学克尔效应的多功能等离子体逻辑器件。克尔效应提供了具有高消光比 (ER) 的马赫曾德干涉仪 (MZI) 输出端口上的光信号切换。输入信号的强度被定义为输入逻辑的不同状态。此外，输出端口处是否存在光信号分别用于设置逻辑“1”和“0”。最后，通过所提出的器件实现了四种不同的逻辑功能，包括可逆Toffoli门（TG）、半加器（HA）、或非门和异或门。通过Opti-FDTD中的时域有限差分法对该装置进行了分析。此外，还从ER、插入损耗(IL)和传输效率方面进行了基本要素的分析。
