Unidirectional vortex waveguides and multistable vortex pairs in polariton condensates
Unidirectional vortex waveguides and multistable vortex pairs in polariton condensates
Vortices carrying quantized topological charges have potential applications in information processing. In this work, we investigate vortex carriers and waveguides in microcavity polariton condensates, nonresonantly excited by a homogeneous pump with intensity grooves. An intensity groove with a ring shape in the pump gives rise to dark-ring states of the …
