TOPIC:		DISCRETE OPTICAL SPATIAL SOLITONS

ABSTRACT:

Motivated by the recent experimental observation of anomalous diffraction
in a linear waveguide array, we propose a novel model governing the
propagation of an optical beam in a diffraction managed nonlinear
waveguide array.

This model supports discrete spatial solitons whose beam width and peak
amplitude evolve periodically.  A nonlocal integral equation governing the
slow evolution of the soliton amplitude is derived and its stationary
soliton solutions are obtained.
