Metasurfaces offer promising structures for controlling the wavefront of light. The development of such structures is evidence for numerous ways to alter on demand light properties such as amplitude, phase, and polarization. However, the simultaneous control of all parameters of light over a wide bandwidth is still a great challenge. With polarization multiplexing, we have achieved the lesser goal of simultaneous control of phase and amplitude over a 1000 nm bandwidth using a plasmonic nanoslit array associated with the traditional detour phase. In a proof-of-concept experiment, we demonstrate 3D object reconstruction and polarization multiplexing images at various prescribed wavelengths from 473 to 1550 nm using a specially designed meta-hologram. Benefiting from high controllability of amplitude, phase, and polarization, meta-holograms offer great potential in future applications such as 3D displays, optical communications, and beam shaping.
