The holographic display has recently garnered much attention as the next-generation image technology, and the research and development thereof is proceeding. In general, to generate a hologram, a spatial light modulator (SLM) is mainly used for amplitude or phase modulation, and a specific optical system must be additionally applied to eliminate DC or conjugate noise. Accordingly, the technology of complex modulation SLM has been continuously studied to reduce the volume of optical system and generate the holograms effectively. Also, Hyperbolic Metamaterial (HMM) has been actively researched because they possess the potential for broadband manipulation of the photonic density of states caused by the excitation of electromagnetic states with high-k modes. Under that characteristics, the HMM will be a great advantage from the viewpoint of light extraction. In this paper, the two dipole coupling structures using HMM is reported and the transmission and modulation characteristics of them are analyzed.
