We argue that it should be possible to observe gap-soliton switching in a system composed of two channel waveguides coupled by microresonators, even when the system is only 50 μm long. We differentiate between gaps that occur because of Bragg reflection and gaps that occur because of the resonance of the microresonators. The latter are characterized by anomalously small group-velocity dispersion and therefore by smaller nonlinear switching intensities.
