Phys. Rev. Lett. 92, 093904 (2004) [4 pages]Gap Solitons in Waveguide ArraysReceived 23 September 2003; published 4 March 2004 Bright and dark spatial gap solitons are demonstrated in waveguide arrays. These gap solitons travel across the array at zero transverse velocity, in complete analogy with stationary (immobile) temporal gap solitons. Furthermore, the launching configuration for observing these stationary gap solitons is shown to be the analog of an “ideal experiment” for observing stationary temporal gap solitons, never observed so far. A clear distinction is established between the family of Floquet-Bloch solitons in general and discrete solitons in particular, and the limiting case of gap solitons. © 2004 The American Physical Society URL:
