The efficient generation of circularly polarized light (CPL) is crucial in information technologies such as optical communications and three-dimensional displays. In nature, many plants animals can transform unpolarized into CPL with chiral helical superstructures, which has inspired the development CPL-related materials devices. Herein, by combining self-assembled nematic liquid crystalline microstructures cellulose nanocrystals geometrical configurations Fresnel lenses, free-standing solid-state cellulosic converging lenses large sizes, circular polarization features, adjustable photonic bandgaps were fabricated at low cost, could produce beams exhibiting dissymmetry factors (g = 2(I L - I R)/(I L+ R)) up to -0.61 ± 0.02 focusing sunlight generate real images distant objects. These results may help guide sources or imaging systems, also suggest a simple method construct multifunctional devices from crystals.
