Abstract.

By using a multiple-scale method, we study the formation of the temporal ultraslow vector optical solitons (USVOS) in a cold lifetime-broadened five-level V type atomic system via electromagnetically induced transparency. And we find that the two orthogonally polarized components of the weak pulsed probe field can evolve into a pair of temporal USVOS. Subsequently, by numerical simulating the collision between two temporal USVOS, we obtain that their collision properties are correlated with their incident angle and initial phase shift. Whether two solitons are in phase or out of phase, their collisions are almost elastic. Especially, when two solitons are parallel input, the collisions between them are periodical. Our results may have potential application in optical information processing and engineering.
