The ever increasing growth of data and the need for data transmission emphasizes the requirement of full-optical telecommunication. Therefore, it seems critical to utilize optical integrated circuits, including optical gates, optical dividers, optical converters, etc. In this regard, we introduce a new structure for OR/NOR logical gate. The OR/NOR logical gate is simulated by applying Mach–Zehnder interferometer (MZI) where switching between bar and cross states is implemented by using the electro-optic properties of Lithium Niobate and coupling mode theory. Two different designs for the OR/NOR basic gate are simulated by OptiBPM software. Simulation results show that designed gates implement OR/NOR logical gate completely acceptable. The advantage of these designed gates is that waveguides have smaller length and do not pass above each other; thereby it would be possible to do layering by using fewer layers. Also, results show that output intensity in ‘1’ logic state is more th...

使用Mach-Zehnder干涉仪实现光学OR和NOR门

数据的不断增长和数据传输的需求强调了全光通信的需求。因此，利用包括光门，光分频器，光转换器等在内的光集成电路显得至关重要。在这方面，我们介绍了一种用于OR / NOR逻辑门的新结构。OR / NOR逻辑门是通过应用Mach-Zehnder干涉仪（MZI）进行仿真的，其中通过使用铌酸锂的电光特性和耦合模式理论在条形和交叉状态之间进行切换。OptiBPM软件对OR / NOR基本门的两种不同设计进行了仿真。仿真结果表明，设计门实现的OR / NOR逻辑门完全可以接受。这些设计的门的优点在于，波导的长度较小，并且不会彼此通过。因此有可能通过使用更少的层来进行分层。此外，结果表明，处于“ 1”逻辑状态的输出强度更高。
