| Abstract | Orbital angular momentum (OAM) has recently gained much interest in high-speed optical communication due to its spatial orthogonality. However, complex spatial phase distributions of OAM make the components difficult for nano-photonic integration. In this work, a method to multiplex and demultiplex multiple OAMs, wavelengths, and polarizations channels by a highly integrated off-axis technique on a metasurface is presented. As a multiplexer, beams without OAM can be transferred into coaxial beams carrying different OAM features by different incident angles; as a demultiplexer, coaxial beams carrying multi-OAMs can be divided into different directions with fundamental modes. Furthermore, the component based on dipole optical antenna metasurface can be used not only as an OAM multiplexer/demultiplexer but also as a multiplexer/demultiplexer to achieve wavelength division multiplexing and polarization-division multiplexing, as both these applications are based on the conservations of momentum and angular momentum. For practical applications, phase-only hologram is analyzed to demonstrate multiple functions of this method. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim |
