Recently, the hologram display has been spotlighting attention as the next generation display technology and research and development are proceeding . Generally, spatial light modulator (SLM) is mainly used for amplitude or phase modulation to generate holograms and it must need additional optical systems, which is applied to eliminate DC or conjugate noise. Therefore, the technique of the SLM for complex modulation has been continuously studied to reduce the volume of the optical system and efficiently generate the hologram. In this paper, we propose a spatial optical modulator source technology with complex modulated single pixel that can modulate amplitude and phase simultaneously using photonic crystal structure with double zero index (DZI) characteristics and effective medium phase delay structure of subwavelength scale [2-3].
