CPC classification number: G02B5/001 , G02B1/002 , G02B2207/101
Abstract: An optical device comprises a substrate and a metasurface. The metasurface comprises a plurality of nanoscale elements disposed on the transparent substrate at different orientations. The orientations of the nanoscale elements define a phase profile such that the nanoscale elements convert an incident light into an output light propagating substantially without diffraction.
Abstract translation: 光学器件包括衬底和元表面。 该转换表面包括以不同方向设置在透明衬底上的多个纳米级元件。 纳米级元件的取向限定了相位分布，使得纳米级元件将入射光转换为基本上没有衍射传播的输出光。
