Abstract: Conventional SLMs for holography can operate on either phase-only or amplitude-only modes, both of which are incomplete. Incomplete modulation of light causes undesirable noises including twin noises and additional filters for elimination of these noises make the system too bulky for practical uses. There have been attempts to realize integrated complex spatial light modulation devices but the possibility of extreme scale-down to sub-micron pixel has not been explored much. In this paper, we numerically investigate a reflection type complex modulation pixel (CMP) based on plasmonic waveguide structure. Our full field electromagnetic simulation indicated that the amplitude and phase of the reflected wave can be modulated by changing two control parameters within reasonable dynamic range.
