摘要

由于先进的基于半导体的光开关器件的发展及其商业化,全光信号处理的概念和技术在过去几年中发生了重大变化。为了在光子计算中实现逻辑运算,需要通用门。在本研究中,使用SOA设计了简单紧凑的全光NAND门,并在10Gbps至40Gbps的高数据速率下进行了模拟。通过对各种输入组合和SOA的数值分析,展示了所提出的NAND门的性能。通过改变波长、注入电流、限制因子以及光源、放大器和滤波器等光学元件,进行了数值分析。对于NRZ-L用户定义的比特序列,在10Gbps数据速率下获得了独特的结果。这种全光NAND门将是光计算领域实现高速光通信网络的完美替代方案。在10Gbps到40Gbps的高速数据速率下实现了11.48dB的消光比。设计的NAND逻辑的输出光谱也被接收用于宽输入光谱,并且系统选择性地响应1548.3nm的输入波长,该输入波长是探测信号波长。

Simulation and Numerical Analysis of SOA Based All Optical NAND Gate for High Data Rate Communication
As a result of the development of advanced semiconductor-based optical switching devices and their commercialization, concepts and technologies in all-optical signal processing have evolved significantly in the past few years. In order to realize logical operations in photonic computing, universal gates are needed. In this research, the simple and compact all-optical NAND gate was designed using SOA and simulated at a high data rate of 10Gbps to 40 Gbps. The performance of the proposed NAND gate is shown by the numerical analysis for various input combinations and SOA. By changing wavelengths, injection currents, confinement factors, as well as optical components such as sources, amplifiers, and filters, a numerical analysis is performed. Unique results were obtained at a 10 Gbps data rate for NRZ-L user-defined bit sequences. This kind of all-optical NAND gate will be the perfect alternative in the field of optical computing to realize a high-speed optical communication network. An extinction ratio of 11.48 dB is achieved at a high-speed data rate of 10 Gbps to 40Gbps. The output spectrum of the designed NAND logic is also received for a wide input spectrum and the system responds selectively for the input wavelength at 1548.3 nm which is the probe signal wavelength.
