Arithmetic logic circuit (ALC) is the basic need of any combinational circuits but traditional digital circuits have limitations in terms of switching speed and power loss. In this paper, we have implemented an optical universal one-bit ALC by utilizing the electro-optic effect of Titanium-diffused lithium niobate (Ti-LiNbO3) based Mach–Zehnder interferometers for high-speed processing combinational circuits. The extinction ratio of proposed design is highest for a 1-bit multiplier, which is 10.10 dB, and insertion loss of 0.362 dB is achieved for borrow logic. The beam propagation method has been used for the modeling and simulation of the proposed design at 1330 nm wavelength. Mathematical computation has been done for the proposed structure and further results were verified by MATLAB simulation.

一种用于高速处理组合电路的光通用一位算术逻辑电路的实现

算术逻辑电路（ALC）是任何组合电路的基本需求，但传统数字电路在开关速度和功率损耗方面存在局限性。在本文中，我们利用基于钛扩散铌酸锂 (Ti-LiNbO3) 的 Mach-Zehnder 干涉仪的电光效应实现了一种用于高速处理组合电路的光学通用一位 ALC。建议设计的消光比对于 1 位乘法器最高，为 10.10 dB，借位逻辑实现了 0.362 dB 的插入损耗。光束传播方法已用于在 1330 nm 波长下对所提议的设计进行建模和仿真。对所提出的结构进行了数学计算，并通过MATLAB仿真验证了进一步的结果。
