Quantitative phase imaging of plasmonic metasurfaces — •Vlastimil Křápek¹, Petr Dvořák¹, Alexander Fassbender², Petr Bouchal¹, Martin Hrtoň¹, Jiří Babocký¹, Filip Ligmajer¹, Radim Chmelík¹, Stefan Linden², and Tomáš Šikola¹ — ¹Central European Institute of Technology, Brno University of Technology, Purkyňova 123, 612 00 Brno, Czech Republic — ²Physikalisches Institut, Universität Bonn, Nussallee 12, 53115 Bonn, Germany

We report on wide-field quantitative phase imaging of plasmonic metasurfaces by coherence-controlled holographic microscopy [1] and 4th generation quantitative optical microscopy. Both resonant [2] and geometric phase [3,4] are retrieved for various metasurfaces including a lens and a vortex beam plate. Three-dimensional imaging, polarization sensitivity, and sensitivity down to single antenna is demonstrated.
