Metasurfaces are optically thin metamaterials that promise complete controlof the wavefront of light but are primarily used to control only the phase oflight. Here, we present an approach, simple in concept and in practice, thatuses meta-atoms with a varying degree of form birefringence and rotation anglesto create high-efficiency dielectric metasurfaces that control both the opticalamplitude and phase at one or two frequencies. This opens up applications incomputer-generated holography, allowing faithful reproduction of both the phaseand amplitude of a target holographic scene without the iterative algorithmsrequired in phase-only holography. We demonstrate all-dielectric metasurfaceholograms with independent and complete control of the amplitude and phase atup to two optical frequencies simultaneously to generate two- andthree-dimensional holographic objects. We show that phase-amplitudemetasurfaces enable a few features not attainable in phase-only holography;these include creating artifact-free two-dimensional holographic images,encoding phase and amplitude profiles separately at the object plane, encodingintensity profiles at the metasurface and object planes separately, andcontrolling the surface textures of three-dimensional holographic objects.
