Figure | Fabrication and measurement results of the inverse-designed structures. a. A painting of sunflowers is represented by structural color. The fabricated chip is about 2.9 x 1.9 mm2 and the sunflowers can be observed directly under a microscope. b. An inverse-designed grating that has a high transmission at around 750 nm and a relatively low transmission at around 650 nm. c. An inverse-designed meta-atom that has different transmission responses under different polarization directions of incident light at around 620 nm. d. Two different patterns are encoded into two different polarization directions at the same wavelength of 620 nm by the three inverse-designed meta-atoms.
