✦ Synopsis

Parametric polariton scattering is investigated in low-dimensional semiconductor microcavities, such as quasi-zerodimensional micro-pillars and quasi-one-dimensional wire structures. In both cases, parametric scattering could be demonstrated in continuous wave experiments. However, the selection rules di er from the planar cavity case, where the total energy and momentum have to be conserved. In quasi-zero-dimensional cavities, momentum conservation does not apply. In quasi-one-dimensional resonators besides energy and momentum, the parity of the involved states has to match with a parity conservation constraint.

We theoretically study the elastic scattering of lower cavity polaritons on the static disorder in high quality semiconductor microcavities in the strong coupling regime. We consider the dominant contribution of the resonant scattering on localized exciton levels and calculate for a model density of

Polariton-polariton scattering is studied in a III-V microcavity (MC) by cw polarized photoluminescence techniques using resonant excitation into the lower polariton (LP) branch. Such excitation conditions allow the parametric process leading to the creation of macroscopic coherent populations of th
