A circular polarization selective microcavity using chiral photonic metamaterials is designed, in which photons of a particular circular polarization dominate in stimulated emissions as a result of cavity resonances. The selection behavior originates from the special chiral reflector, which exhibits two elliptical polarization eigenstates almost identical to the same circular polarization. Theoretical analysis by using Jones matrix is given to explain this interesting phenomenon in detail. A lasing mode with an almost perfect circularly polarized field is present inside this cavity and observable at the output.
