Reflective Metasurface and Plasmonic Hologram Application

Abstract

Holograms, the optical devices to reconstruct pre-designed images, have been advanced dramatically with the development of today’s nanotechnology [1-2]. However, applications of hologram are still limited by the constituent materials, and their working range is rather narrow. In the past decade, plasmonic metamaterials [3] have attracted many attentions, which exhibit strong variations in their reflectance and/or transmittance spectra. Moreover, metasurfaces show the abilities to exhibit extraordinary light-manipulation abilities [4-5]. In this paper, we reported the high-efficiency and broadband meta-hologram consisted of plasmonic metamaterials, which functions for both coherent and incoherent light sources within a broad spectral range under a wide range of incidence angles [6].
