Abstract Langmuir-Blodgett photonic hetero-structures were studied using experimental methods and computer modeling. Photonic properties were created by alternating deposition of multimolecular layers of PVDF/TRFe copolymer and azo-dye compound onto a glass substrate. According to computer modeling the photonic zone in a spectral range of 700-800 nm has been observed. The created photonic structures are characterized by unique functional properties of both copolymer and azo-dye multilayers. Individually these layers show ferroelectricity (PVDF/TRFe layers) and an effect of photo-induced optical anisotropy (the layers of azo-dye compound). The latter properties open new possibilities in controlling the photonic properties by external electric fields and polarized light radiation.
