Evidence for Bose Einstein condensation (BEC) of exciton-polaritons have been presented recently by several groups in a variety semiconductor microcavity geometries (eg. [1). Objections nevertheless remain as experimental evidence for polariton BEC bear striking similarity to observed behavior in a regular photon laser or microcavity in weak coupling regime [2]. Latest results however show that a both BEC and lasing transitions can occur and are distinguishable in the stress trapped case [3]. \\[3pt] [1] Balili, R., Hartwell, V., Snoke, D., Pfeiffer L., and West, K.
