Coexistence of low threshold lasing and strong coupling in microcavities

By P.G. Lagoudakis, M.D. Martin-Fernandez, J.J. Baumberg, G. Malpuech and A. Kavokin


We report the coexistence of low threshold lasing and strong coupling in a high-quality semiconductor microcavity under near-resonant optical pumping. A sharp laser mode splits from the lower-polariton branch and approaches the bare cavity mode frequency as the pump power increases. The lasing is produced by low density localized exciton states, which are weakly coupled to the cavity mode. The appearance of this lasing mode distinguishes quantum-well excitons into those which are strongly or weakly coupled with the cavity mode
