Polarization of light reflected by cholesteric blue phases

Blue phases (BPs) are cubic phases of cholesteric liquid crystals (CLC) with a sufficiently short pitch. They occur in three different phases (BPI, BPII, BPIII) in small temperature ranges between the cholesteric and the isotropic state. Light reflected by BP crystals is partially circularly polarized. Calculating the Muller matrices of the Bragg reflected light for different structural models makes it possible to compare the results with measurements and study other theoretical considerations. Specifically, Muller matrices for a polycrystalline specimen were analysed.
