Giant enhancement of THz-frequency optical nonlinearity by phonon polariton in ionic crystals

Optical nonlinearity in the THz range is of interest for scientific applications. Here the authors show that THz nonlinearity in ionic crystals can be enhanced by orders of magnitude through phonon polaritons, which is also described by nonlinear modified Huang equations.
