In this work, we realize spin polarized edge emission from polariton condensates formed in single-crystal perovskite microwires, which act as natural cavities. Above threshold, we detect a clear waveguided optical spin Hall effect in both real - and reciprocal-space, with pseudospin phase-locking mediated by coherence between opposite edges.
