Interbranch parametric oscillation in the weak coupling regime for semiconductor vertical multimicrocavities

Abstract

We develop a model able to properly describe a variety of optical parametric oscillations (OPOs) in some recently realized vertical semiconductor multimicrocavities. Our model shows that, contrary to the case of a conventional single microcavity, the OPO can take place even when the system is brought in the weak light-matter coupling. Our predictions agree qualitatively with experiments; they show some OPO configurations which are peculiar of the weak coupling and suggest some experiment. The model clearly shows the need to have a better understanding of optical parametric oscillations in this regime.
