We investigate active spatial control of polariton condensates independently the polariton-, gain-inducing excitation profile. This is achieved by introducing an extra intracavity semiconductor layer, non-resonant to cavity mode. Saturation optical absorption in uncoupled layer enables ultra-fast modulation effective refractive index and, through excited-state absorption, dissipation. Utilising these mechanisms, we demonstrate over profile and density a condensate at room temperature.
