【 摘 要 】

We demonstrate the possibility to build stable Josephson pi-junction stripes with exciton-polariton condensates. The stability of the pi junction between arbitrary long polariton stripes is achieved at low pumping by balancing the snaking instability with counterpropagating flows towards the junction. Not dissimilar from a dark soliton, the instability becomes relevant at high pumping leading to formation of vortex dipoles. The resulting structures can be stabilized to produce static lattices of Josephson vortices in straight and ring geometries.
