We have utilized various designs to study plasmonic thermal emitters, surface-enhanced Raman scattering substrate, nonlinear frequency conversion, etc. In addition to strong field confinement, those nano-scatterers are capable of manipulating the phase response of the scattering light, which provides additional degree of freedom to accomplish polarization control and wavefront shaping. This leads to the field of metasurfaces developing various resonant mechanisms to achieve a phase coverage ranging from 0 to 2π. These metasurfaces are applied to demonstrate ultrathin and lightweight optical meta-devices such as achromatic meta-lenses and versatile polarization converters.
