Nonlinear magneto-optic spatial solitons

Nonlinear magneto-optics and the propagation of light beams are introduced through the use of layered structures. Linear magnetoopotic layers are deployed with varying degrees of complexity in structures that have components that can become optically nonlinear. The properties of spatial solitons in the presence of interfaces are investigated and some new ideas using magnetooptic materials to control spatial solitons are introduced. Some comments on the range of modern magnetooptic materials are made, followed by a derivation of envelope equations for TM modes. The control of spatial solitons through the use of current- strip electrodes is simulated and an interesting split-field method of generating perturbative analytical results is presented. It is emphasized that these systems are very easy to create experimentally to any degree of sophistication. The approach, therefore, is very promising for future all-optical processing.
