We prepared polymer thin film on a diffraction grating by electrochemical polymerization in cholesteric liquid crystal (ChLC). The polymer thin film synthesized in ChLC shows diffraction function due to periodic structure produced by imprinting of the matrix ChLC. Combination of diffractions from the substrate (prepared by top-down technique) and the polymer having fingerprint structure (prepared by bottom-up technique) provides double diffraction grating function.
