We calculate the effects of polariton bi- and multistability in a semiconductor Bragg microcavity with multiple quantum wells and a chiral photonic crystal on the upper mirror for resonant coherent pumping normal to the structure. Even if the system is not optimized for obtaining photoluminescence with a high degree of circular polarization in the spontaneous mode, it is shown that linear-polarized pumping can cause nonlinear switching to states with a degree of circular polarization of polaritons up to 90%. Calculations were performed in both the mean-field and self-consistent approximations, accounting for the difference in exciton density among the microcavity's quantum wells.
