Abstract: Chiral liquid crystal materials can self-organize into modulated structures with multilevel arrangement formed by curved cholesteric helixes and spatially ordered defects.We managed to prepare periodic twodimensional cholesteric domains with remarkable structure and photonic properties.They are formed due to geometrical frustration.Complex optical patterns with non-trivial dependence of the images on light polarization and on observation geometry were found and investigated in transmission and reflection.The obtained photonic structures of two-dimensional ordered confocal domains and their optical properties are a challenge both for theory and experiment.
