Query: Competition between horizontal and vertical polariton lasing in planar
  microcavities   Planar microcavities filled with active materials containing excitonic
resonances host radiative exciton-polariton (polariton) modes with in-plane
wave vectors within the light cone. They also host at least one mode guided in
the cavity plane by total internal reflection and which is not radiatively
coupled to the vacuum modes except through defects or sample edges. We show
that polariton lasing mediated by polariton stimulated scattering can occur
concomitantly in both types of modes in a microcavity. By adjusting the
detuning between the exciton and the radiative photon mode one can favor
polariton lasing either in the radiative or in the guided modes. Our results
suggest that the competition between these two types of polariton lasing modes
may have played a role in many previous observations of polariton lasing and
polariton Bose Einstein condensation.
