Metasurface is a class of two-dimensional microstructure functional materials, which has an ability of modulating light in subwavelength region and becomes a hot topic during the last decade. An advantage of metasurfaces is their versatility by invoking the degrees of freedom of light field to achieve various functionalities. In this paper, we report methods of using the polarization and dispersion of light to achieve multifunctional metasurface devices, allowing the different degrees of freedom of light to carry independent phase profiles to achieve the polarization-dependent conversion of Bessel beams with different orders and numerical apertures as well as integrated optical tweezers-optical spanner metasurface. Also, the wavelength-controlled multifunctional metalens by introducing an improved genetic algorithm has been implemented. We envision our research are expected to be the potential candidates in multifunctional integrated optical devices.
