Visible Light Broadband Achromatic Metalens Based on Variable Height Nanopillar Structures

Visible Light Broadband Achromatic Metalens Based on Variable Height Nanopillar Structures

Metalenses have excellent modulation capabilities in terms of phase, amplitude, and polarization of light, significantly reducing the size and complexity of imaging systems, and showing great application prospects. However, like traditional optical meta-atoms, ordinary metalenses suffer from a signi...
