Numerical simulations and an analytic approach based on transmission line theory are used to design splitters for nano-plasmonic signal processing that allow to arbitrarily adjust the ratio of transmission from an input into two different output arms. By adjusting the geometrical parameters of the structure, either a high bandwidth or a sharp transmission resonance is obtained. Switching between the two arms can be achieved by modulating the effective refractive index of the waveguide. Employing the instantaneous Kerr effect, switching rates in the THz regime are potentially feasible. The suggested devices are of interest for future applications in nanoplasmonic information processing.
基于传输线理论的数值模拟和解析方法被用于设计用于纳米等离子体信号处理的分离器，该分离器能够任意调整从一个输入端到两个不同输出臂的传输比率。通过调整结构的几何参数，可以获得高带宽或尖锐的传输共振。通过调制波导的有效折射率可以实现两个臂之间的切换。利用瞬时克尔效应，太赫兹频段的切换速率在理论上是可行的。所提出的器件对于纳米等离子体信息处理的未来应用具有重要意义。
