Metasurface Holograms

View this OSA Technical Group webinar on-demand by selecting 'Metasurface Holograms' under Recordings.

Meeting Description:

Metasurfaces are two-dimensional metamaterials composed of subwavelength photonic 'atoms', and they have attracted great interest owing to their numerous functionalities and potential to modify electromagnetic characteristics. Metasurfaces are expected to pave the path for high quality spatial light modulators that can potentially overcome the limitations of conventional optical components for holography.

In this webinar hosted by the OSA Holography and Diffractive Optics Technical Group, Dr. Byoungho Lee of Seoul National University will present general concepts of metasurface and their applications. Then one of the promising applications of metasurfaces, "metaholograms," will be explained with their previous and recent advances. Introductions and motivations for a complex-amplitude modulation, which means both amplitude and phase modulation, will be covered in this webinar by Dr. Lee, and a novel metasurface for complex-amplitude modulations will be demonstrated. Finally, current issues and required improvements for the future of metaholograms will be suggested with conclusions.

What You Will Learn:

  • General concepts of metasurfaces and their applications for holographic devices

Who Should Attend:

  • Holographic researchers who want to know principles and status of metasurface holograms
  • People willing to learn metasurfaces and their applications
  • Researchers on nanophotonics and metamaterials who want to know issues of holographic applications
