Slow-light optical bullets in arrays of nonlinear Bragg-grating waveguides

Sukhorukov, Andrey; Kivshar, Yuri


We demonstrate that propagation direction and velocity of optical pulses can be controlled independently in the structures with multiscale modulation of the refractive index in transverse and longitudinal directions. We reveal that, in arrays of waveguides with phase-shifted Bragg gratings, the refraction angle does not depend on the speed of light, allowing for efficient spatial steering of slow light. In this system, both spatial diffraction and temporal dispersion can be designed...[Show more]
