Abstract


Considerable attention has been devoted to a nonlinear waves propagation in various wave-guide structure due to their applications in photonic-microwave devices . In this communication, the dispersion characteristics of transverse magnetic polarized waves nonlinear guided waves propagating in a multilayer semiconductor superlattices waveguide surrounded by one side by a nonlinear magnetic cover have been investigated theoretically. The two sublattice uniaxial antiferromagnetic crystal is considered as a nonlinear magnetic medium where the permeability is treated as a function of the magnetic field. Nummerical results are demonstrated for a waveguiding system containing some number of layers of superlattices. We hope that our present work could lead to several extensions and promising applications in future technology.
