| 英文摘要 | Metasurfaces constructed from function-driven artificial meta-cells possess great flexibility in tuning effective electric permittivity and magnetic permeability leading to excellent performance on the manipulation of electromagnetic waves. Here polarization-independent dielectric metasurfaces are presented as beam deflectors and meta-lenses working on telecommunication wavelength based on non-resonant metamolecules. A conversion efficiency as high as 70.5% is achieved when beam deflection angle theta = 18.45 degrees. With precisely designed parameters a planar lens with the focal length of 30.85 mu m shows that focusing efficiency as high as 47.3% is realized. The meta-lens yields a NA = 0.63 and a full-width at half-maximum (FWHM) = 1.64 mu m at 1.55 mu m. With broadband and wide-angle focusing properties the polarization-insensitive metasurfaces promise great applications in high sensitivity single photon detector and other opto-electronic integrated devices. |
