GO metalens thickness

Caption

(a) Schematic figure of GO metalens on a glass substrate, the total thickness is 200 nm. When reduced by femtosecond laser in RGO area, the absorption and refractive index increase while the thickness is reduced to 100 nm. Normalized intensity distribution in the x-z plane from theoretical calculation of the focusing characterization of (b) axial multifocal spots GO metalens and (c) optical needle GO metalens, respectively.
