Abstract
Stable out-of-phase soliton-like distributions of the wave field with few-cycle durations are found in fibers consisting of a rectangular lattice of weakly coupled cores. The stability of found distributions for durations larger than the critical value is shown analytically and numerically. Numerical simulation shows that the radiation of linear dispersive waves rather quickly transforms shorter pulses to the found solution with critical duration.
