Abstract

Theoretical and experimental results on optical ring dark solitary waves are presented, emphasizing the interplay between initial dark beam contrast, phase-shift magnitude, background-beam intensity and saturation of the nonlinearity. An enhanced RDSW transverse dynamics originating in the interaction with a second coaxial dark beam is analyzed theoretically in a good agreement with the experiment. The results may open the way to construct a parallel all-optical three-position radial switch.
