Chiral polariton lasing is a source of circularly polarized, energy-efficient coherent emission. However, generating high optical contrast opposite handedness challenging because excitonic gain materials show low circular dichroism at room temperature. In addition, highly chiral requires the symmetry cavities to be broken, which can affect resonance quality and result in low-chiral purity. Here, we report how plasmonic nanoparticle lattice having mismatched dimer unit cells strongly coupled CdSe nanoplatelets facilitate with threshold fluences (8 μJ/cm2) purity (∼0.92). This least two times lower than that other systems temperature, chirality approaches theoretical maximum. These room-temperature characteristics are promising for using broad range applications, from spintronics optoelectronics quantum information processing.
