About This Webinar
Metasurfaces are optical elements that consist of sub-wavelength features on a planar substrate. With appropriate design, metasurfaces can be tailored to achieve a variety of optical functions, spanning both traditional use cases and emerging technologies. As a consequence, they have gathered considerable interest across the automotive, medical, and consumer electronic markets. Although metasurfaces supply an exceptionally flexible platform to offer solutions in these domains, system-level requirements enforce limits on the scope of their practical implementation. Additionally, in order to supply such large markets, several process technologies are being developed to transition the fabrication of metasurfaces from current lab-scale demonstrations to consumer-level production volumes.

After an introduction to the principles of metasurfaces, Pawel Latawiec provides insights into their practical implementation. He focuses on the role metasurfaces can play in 3D-sensing for consumer electronics, highlighting the step-change improvements they deliver in form and function. Additionally, he explores how high-volume semiconductor foundries can be leveraged to produce metasurface optical elements en masse and provides a cursory overview of the unique challenges and opportunities metasurfaces offer.
