In this study, we propose a novel, to the best of our knowledge, all-optical Galois field (AOGF) adder that utilizes logic all-optical XOR gates. The design is founded on optical beams' constructive and destructive interference phenomenon and incorporates the phase shift keying technique within a two-dimensional linear photonic crystal (2D-LPhC) structure. The suggested AOGF adder comprises eight input ports and four output ports. We employ the finite difference time domain (FDTD) procedure to obtain the electric field distribution in this structure. The FDTD simulation results of the proposed AOGF adder demonstrate that the minimum and maximum values of the normalized power at ON and OFF states ( , ) for the output ports are 95% and 1.7%, respectively. Additionally, we obtain different functional parameters, including the ON-OFF contrast ratio, rise time, fall time, and total footprint, which are measured at 17.47 dB, 0.1 ps, 0.05 ps, and 147µ , respectively.
在本研究中，据我们所知，我们提出了一种新颖的全光伽罗瓦域（AOGF）加法器，它利用逻辑全光异或门。该设计基于光束的相长干涉和相消干涉现象，并在二维线性光子晶体（2D-LPhC）结构中纳入了相移键控技术。所提出的AOGF加法器包括八个输入端口和四个输出端口。我们采用时域有限差分（FDTD）方法来获得该结构中的电场分布。所提出的AOGF加法器的FDTD模拟结果表明，输出端口在开态和关态（ ， ）下归一化功率的最小值和最大值分别为95%和1.7%。此外，我们还获得了不同的功能参数，包括开-关对比度、上升时间、下降时间和总面积，分别测量为17.47 dB、0.1 ps、0.05 ps和147µ 。
