Summary
Can a spatially extended photonic lattice support spin-controlled lasing?
Patterns a GaAs/InGaAs microcavity and combines polarization-resolved measurements with modal and rate-equation models.
Reports pump-controlled handedness and coherence over multiple lattice cells as the system enters photon lasing.

Commentary
The pump is optical; a transition out of strong coupling must not be conflated with polariton condensation.
Brings together periodic geometry, active layers and polarization control—the central ingredients of the original research.
