We present the alliance of the interleaved phased antenna array and spin-enabled optics of dielectric nanoantennas incorporated within a two-dimensional nanophotonic system, enabling the detection of the fundamental properties of light.
Multitasking shared-aperture systems have initially emerged as radar phased array antennas. Recently, the shared-aperture concept has been suggested as a platform for multifunctional optical phased array antennas, accomplished by a reflective metasurface [1]. Metasurfaces consist of metallic or dielectric subwavelength nanoantennas, capable of manipulating light by controlling the local amplitude...
We incorporate the shared-aperture phased antenna array concept and spin-controlled two-dimensional optics based on nanoantennas. By use of the geometric phase mechanism, utilizing the spin-orbit interaction phenomenon, a multifunctional metasurface is implemented. The shared-aperture metasurface platform opens a pathway to novel types of nanophotonic functionality.
We report on a spin-based surface plasmon directional excitation by spinoptical Rashba metasurfaces. The light-matter interaction control via the geometric design of the metasurface symmetry ushers in a new era of light manipulation.
We report on spinoptical metamaterials manifested by spin-controlled optical modes, where the inversion symmetry is violated. The metasurface symmetry properties design via nanoantennas is a starting point for spin-based nanophotonic applications.
