| 摘 要： | In this Letter,we fabricate integrated metasurface of encoded dynamic phases and experimentally generate nonconventional Kagome-type lattices of no-second-order phase vortices.The thin metasurface acts analogous to an integration of three conventional optical elements,i.e.,six pinholes located at the vertices of two concentric regular triangles of size ratio 1:2,six transparent discs of different thicknesses to introduce a total phase shift difference of 6π,and a Fourier lens with a focal length in the micro-scale.A Kagome lattice with the required vortex distribution is realized at the"focal"plane of the metasurface under illumination of the plane wave.
