Optical receiving antenna for indoor visible light communication based on holographic mirror

A novel method for the design and production of the optical receiving antenna was proposed. The hologram called Holographic Mirror, which has the dual function of gathering beam and filtering ambient wave, is made from holographic material by using the principle of interference and diffraction. The angular selectivity, spectral selectivity and diffraction efficiency at any point of the novel optical receiving antenna have been analyzed by coupled wave theory and k vector closed legitimate, the results of simulation show that the field of view and spectral bandwidth at different points of the Holographic Mirror are 0.8°~13.4° and 4.4 nm~7.4 nm respectively, and the overall diffraction efficiency of more than 95.3%. Compared with the combination of a converging lens and a filter into the conventional optical receiving antenna, small size, light weight, and low cost of the holographic mirror can be used as optical receiving antenna for indoor visible light communication.
