Abstract

Gap solitons can occur in nonlinear periodic stacks. They would, in general, be created using a powerful external light pulse. In doing so it is important that the external energy required be minimized. It is shown that, among other things, the refractive indices of the stack and of the surrounding media play a crucial role in determining the efficiency. Particularly important also are the parameters of the outer layers of the nonlinear stack.
