Abstract: A zooming control device includes a filter assembly, a metalens device spaced apart from the filter assembly, and a polarization selection device between the filter assembly and the metalens device. The filter assembly is configured to select a wavelength of light exiting the filter assembly and includes an optical device having an adjustable refractive index that varies with an electric current applied to the optical device. The polarization selection device is configured to select a polarization state of the light exiting the filter assembly and passing through the polarization selection device.

Abstract: A metasurface optical device includes a substrate and a nano-structure layer. The nano-structure layer is arranged on the substrate and includes a plurality of photonic crystal units. Each photonic crystal unit includes a plurality of nano-structure units arranged on the substrate such that an energy bandgap is formed in a cross-section of the photonic crystal unit parallel to the substrate. The energy bandgap surrounds the center area of the cross-section.

Abstract: A metasurface optical device includes a substrate and a nano-structure layer disposed on the substrate. The nano-structure layer includes a plurality of nano-structure units. The plurality of nano-structure units extend in a direction away from the substrate, and central axes of the plurality of nano-structure units form corresponding angles with respect to a normal direction of the substrate, such that the plurality of nano-structure units are arranged obliquely relative to the substrate.
