FIG. 4.
Metasurface nanoprinting with chiral shadow rendering of structured light. (a) Experimental setup for measurement. A laser beam at the wavelength of 550 nm is collimated and incident on the metasurfaces though a linear polarizer (LP) and quarter wave plate (QWP). The images of metasurface nanoprinting can be captured by the standard microscope attached with a camera. (b) Experimentally captured optical images of the metasurface nanoprinting illuminated with LCP and RCP light.
