Delivering Flat Optics Solutions From Design to Mass Production

Presentation will begin: Tuesday, January 10, 2023 - 10:55 AM EST
Presented by: Theodor Nielsen, NIL Technology

Metaoptics is a flat optics technology that uses an array of subwavelength nanostructures to bend and steer light. A typical metalens can use an array of sub-100-nm-diameter pillars to implement the functionality of multiple refractive lenses. When used in near-infrared applications, these metapillars are made of amorphous silicon on a glass substrate, making these lenses thin, strong, rigid, and thermally stable.

Depth sensing applications in smartphones, consumer electronics, autonomous vehicles, and augmented reality require highly compact, lightweight, and high-performance illumination and camera systems. Nielsen discusses the optical technologies required for time-of-flight systems, ultracompact eye tracking, automotive driver monitoring systems, AR optical waveguides, and shortwave IR for medical and multispectral applications.

Meta-optical elements (MOEs) can be produced using e-beam lithography to develop masters, followed by nanoimprint technology to fabricate high-quality, low-cost elements in mass production. Nielsen covers every step in the production process, from design to master, to replication and characterization — all within a six-week cycle.
