The proposed all-optical circuit utilizes the deep sub-wavelength confinement properties of plasmonic metal–insulator–metal waveguides. All-optical priority encoder accepts \({2}^{n}\) inputs and produces \(n\) outputs. The priority encoder is designed using the plasmonics waveguide-based Mach–Zehnder interferometer (P-MZI). The P-MZI works as an all-optical switch. The switching of the signal depends on the power of the applied optical input signal. This waveguide has a nonlinear material inside. The proposed work is analyzed using the finite-difference time-domain method, and a mathematical description is also given. Parameters such as insertion loss and extinction ratio are reported as 15.82 dB and 0.57 dB, respectively.

使用等离子体波导的全光优先编码器分析

所提出的全光电路利用等离子体金属-绝缘体-金属波导的深亚波长限制特性。全光优先编码器接受\({2}^{n}\)输入并产生\(n\)输出。优先编码器是使用基于等离子体波导的 Mach-Zehnder 干涉仪 (P-MZI) 设计的。P-MZI 用作​​全光开关。信号的切换取决于所施加的光输入信号的功率。该波导内部具有非线性材料。使用有限差分时域方法分析了所提出的工作,并给出了数学描述。插入损耗和消光比等参数分别报告为 15.82 dB 和 0.57 dB。
