Abstract: We analyze an inherent nonlinearity of Surface Plasmon Polaritons at theinterface of Fermi-Dirac metal plasma, stemming from the depletion of electrondensity in high-field intensity regions. The derived optical nonlinearcoefficients are comparable to the experimental values for metals. We calculatethe dispersion relations for the nonlinear propagation of high-intensitySurface Plasmon Polaritons, predicting a nonlinear induced cutoff and vanishinggroup velocity.
