Abstract: The ability of arbitrarily controlling light’s phase, amplitude, polarization status, frequency, dispersion and so on with metasurface attracts researchers from different fields to design optical devices according to any specific requirements. With the recent burgeoning developments in metasurface, ultra-compact, miniaturized photonic devices with high-quality and spectacular multi-functionalities are highly desired. This thesis mainly focuses on the study of light manipulation through binary metasurface and presents unprecedented applications for optical devices via binary metasurface. Firstly, a new design paradigm for the inverse design of complex binary-amplitude-controlled metasurface is proposed. Based on this, complex meta-holograms with high fidelities and multi-channel encoded meta-holograms are realized. Meanwhile, orbital angular momentum (OAM) as another degree of freedom to realize multi-functional devices is also explored. Multi-mode OAM generation based on kaleidoscopic nanosieves for both on-chip and free-space OAM manipulation is demonstrated. Apart from this, a multi-dimensional reconfigurable continuous OAM generator based on an aperiodic spiral slit grating is designed and demonstrated.
