Anisotropy and Controllable Band Structure in Suprawavelength Polaritonic Metasurfaces
Abstract : In this Letter, we exploit the extended coherence length of mixed plasmon-exciton states to generate active metasurfaces. For this purpose, periodic stripes of organic dye are deposited on a continuous silver film. Typical metasurface effects, such as effective behavior and geometry sensitivity, are measured for periods exceeding the polaritonic wavelength by more than one order of magnitude. By adjusting the metasurface geometry, anisotropy, modified band structure, and unidimensional polaritons are computationally simulated and experimentally observed in reflectometry as well as in emission.
