Quantitative 3D phase imaging of plasmonic metasurfaces

Original language description

Coherence-controlled holographic microscopy (CCHM) is a real-time, wide-field, and quantitative light-microscopy technique enabling 3D imaging of electromagnetic fields, providing complete information about both their intensity and phase. These attributes make CCHM a promising candidate for performance assessment of phase-altering metasurfaces, a new class of artificial materials that allow to manipulate the wavefront of passing light and thus provide unprecedented functionalities in optics and nanophotonics. In this paper, we report on our investigation of phase imaging of plasmonic metasurfaces using holographic microscopy. We demonstrate its ability to obtain phase information from the whole field of view in a single measurement on a prototypical sample consisting of silver nanodisc arrays. The experimental data were validated using FDTD simulations and a theoretical model that relates the obtained phase image to the optical response of metasurface building blocks. Finally, in order to reveal the full potential of CCHM, we employed it in the analysis of a simple metasurface represented by a plasmonic zone plate. By scanning the sample along the optical axis we were able to create a quantitative 3D phase map of fields transmitted through the zone plate. The presented results prove that CCHM is inherently suited to the task of metasurface characterization. Moreover, as the temporal resolution is limited only by the camera framerate, it can be even applied in analysis of actively tunable metasurfaces.
