Slow light in nonlinear Bragg-grating structures

The speed of light can be dramatically reduced in photonic structures with a periodic modulation of the optical refractive index such as Bragg-gratings. We suggest the designs of structures which dispersion properties are optimized for the flexible control of slow light. We then demonstrate that by taking advantage of the enhanced nonlinear pulse self-action in the slow-light regime, it becomes possible to simultaneously suppress the dispersion-induced pulse broadening in time and in space, and realize efficient control of both the magnitude and direction of the pulse velocity. We discuss the possible applications of these effects to power-controlled routing, shaping, and switching of slow light in nonlinear Bragg-grating structures.
