Tm nonlinear electromagnetic waves in semiconductor superlattices waveguiding systems s

Abstract EN

Considerable attention has been devoted to a nonlinear waves propagation in various wave-guide structure due to their applications in photonic-microwave devices [1? 5].

In this communication, the dispersion characteristics of transverse magnetic polarized TM wave’s nonlinear guided waves propagating in a multilayer semiconductor super lattices waveguide surrounded by one side by a nonlinear magnetic cover have been investigated theoretically.

The two sub lattice uniaxial antiferromagnetic crystal is considered as a nonlinear magnetic medium where the permeability is treated as a function of the magnetic field.

Numerical results are demonstrated for a wave guiding system containing some number of layers of super lattices.

We hope that our present work could lead to several extensions and promising applications in future technology.
