使用具有非线性边界条件的麦克斯韦方程的微扰展开，导出了通用传播方程来描述石墨烯表面等离子体（GSP）波导中的非线性效应，包括脉冲的光谱展宽。证明了在 2 5 nm 宽和 1 5 0 nm 长的波导中峰值功率为 0: 5 mW 的初始 1 0 0 fs 脉冲具有相当大的光谱展宽。生成的超连续谱覆盖了 6 μm 到 13 μm 的光谱范围。
Using perturbation expansion of Maxwell equations with the nonlinear boundary condition, a generic propagation equation is derived to describe nonlinear effects, including spectral broadening of pulses, in graphene surface plasmon (GSP) waveguides. A considerable spectral broadening of an initial 1 0 0 fs pulse with 0 : 5 mW peak power in a 2 5 nm wide and 1 5 0 nm long waveguide is demonstrated. The generated supercontinuum covers the spectral range from 6 mu m to 13 mu m.
