Nonlinear surface magnetoplasmon waves on a semiconductor

Nonlinear stationary states of magnetoplasmon waves on a semiconductor-dielectric interface are calculated. A linear n-type gyroelectric semiconductor substrate is assumed to be coated with strongly nonlinear, Kerr-like material. Finite-element numerical solutions are presented in the form of non-reciprocal dependence of the effective wave index on the total power flow. The examples illustrate the relationship of the nonlinearity to the non-reciprocity introduced by the applied magnetic field. The variation of the applied magnetic field, the frequency or the plasma frequency, shows that interesting tuning of the nonlinear guided waves is possible.
