等离子体激元的非局域有质动力非线性

Non-local Ponderomotive Nonlinearity in Plasmonic

Pavel Ginzburg, Alex Hayat, Nikolai Berkovitch, Meir Orenstein

摘要:

我们分析了费米-狄拉克金属等离子体界面处表面等离子体激元的固有非线性,这是由于高场强区电子密度的耗尽引起的。导出的光学非线性系数与金属的实验值相当。我们计算了高强度表面等离子体激元非线性传输的色散关系,预测了非线性诱导截止和消失的群速度。

英文摘要:

We analyze an inherent nonlinearity of Surface Plasmon Polaritons at the interface of Fermi-Dirac metal plasma, stemming from the depletion of electron density in high-field intensity regions. The derived optical nonlinear coefficients are comparable to the experimental values for metals. We calculate the dispersion relations for the nonlinear propagation of high-intensity Surface Plasmon Polaritons, predicting a nonlinear induced cutoff and vanishing group velocity.
