Invited Article: Direct phase mapping of broadband Laguerre-Gaussian metasurfaces
Original language description
We report on the fabrication of metasurface phase plates consisting of gold nanoantenna arrays that generate Laguerre-Gaussian modes from a circularly polarized Gaussian input beam. The corresponding helical phase profiles with radial discontinuities are encoded in the metasurfaces by the orientation of the nanoantennas. A commonpath interferometer is used to determine the orbital angular momentum of the generated beams. Additionally, we employ digital holography to record the detailed phase profiles of the Laguerre-Gaussian modes. This method allows a simple and direct quantitative comparison of the measured phase profiles of the generated Laguerre-Gaussian beams with the theoretically expected phase profiles. Experiments with different laser sources demonstrate the broadband operation of the metasurfaces
