Holograms Gain Efficiency from Metasurface Fabrication Technique

Facebook Twitter LinkedIn Email Comments
CAMBRIDGE, Mass., May 16, 2016 — Nanostructured metasurfaces have been incorporated into compact holograms, enabling the production of different images depending on the polarization of incident light. The highly efficient holograms lose very little light in the processing of creating the image, and are expected to improve antifraud holograms as well as those used in displays. Broadband and chiral binary dielectric metaholograms produce 3D images across different spectrums of light. Courtesy of the Capasso Lab. "By using incident polarized light, you can see far a crisper image and can store and retrieve more...Read full article
