Highly efficient beam splitter based on all-dielectric metasurfaces

The recent exploration of metasurfaces reveals potential for developing virtually flat optics. In this work, a highly efficient beam splitter based on all-dielectric metasurfaces is demonstrated for visible light by finite-difference-time-domain simulations. The structure consists of a TiO2 nano-cyl...
