Abstract
A gap soliton can be controlled by introducing a perturbation into a waveguide structure that includes an otherwise essentially periodic variation of its refractive index. In one embodiment of our invention, by controlling the amplitude, phase and/or average value of the refractive index of a first perturbation, and by maintaining the speed of the soliton below a certain critical speed, we have found that the soliton will transfer its energy to the modes of the perturbation. When the soliton transfers essentially all of its energy in this way, we refer to the soliton as being trapped or captured by the perturbation. Trapped gap solitons enable a variety of unique system applications in, for example, memories, buffers, switches and WDM demultiplexers.
