Abstract
We propose a liquid-crystal-filled microcavity system that enables polarization-selective control of exciton-polariton condensates. The structure consists of a microcavity with embedded perovskite layers, which are positioned to couple independently with orthogonally polarized cavity modes. This configuration allows for the engineering of independent stationary potentials for different polarization components. Using topology optimization, we design these potentials to shape the spatial distribution of polariton condensates, enabling smooth intensity gradation encoding in the emission profile. Our approach provides a versatile platform for polarization-sensitive optical processing and spatial light modulation.
