Abstract

Metasurfaces have been widely studied for arbitrary manipulation of the amplitude, phase and polarization of a field at the sub-wavelength scale. However, realizing a high efficiency metasurface with simultaneous and independent control of the amplitude and phase in visible remains a challenge. In this work, an ultrathin single-cell dielectric metasurface which can modulate complex amplitude in transmission mode is proposed. The amplitude is controlled by adjusting the dipoles and quadrupoles by tuning the geometric size, while the phase is manipulated based on the Pancha-ratnam-Berry phase (also called geometric phase) by rotating the meta-atom. It has been experimentally demonstrated that the quality of holographic image of complex-amplitude hologram en-coded on the proposed metasurface is better than that of phaseonly holograms (generated by angular spectrum method and Gerchberg-Saxton algorithm). The proposed metasurface expands the superior limits of various applications, including arbitrary beam shaping, 3D biological imaging, optical computing, and optics-on-chip devices.
