A new kind of lens for tiny cameras

A UW team led by Karl Böhringer and Arka Majumdar has developed a tunable lens made of metasurfaces and actuated by microelectromechanical systems (MEMS).

Optics startup Tunoptix wins federal grant to develop metalenses for imaging satellites at Washington Nanofabrication Facility

A portion of the team’s experimental setup for capturing an image using a metalens. The researchers capture an image of flowers through a metalens (mounted on a microscope slide) and visualize it through a microscope.

Tunoptix, an optics startup co-founded by University of Washington (UW) electrical and computer engineering professors Karl Böhringer and Arka Majumdar, was awarded $223,000 in Small Business Technology Transfer (STTR) funding from the Defense Advanced Research Projects Agency (DARPA) to develop metasurface lenses (or metalenses) for imaging in satellites at the UW Washington Nanofabrication Facility.

New metasurface design can control optical fields in three dimensions

A team led by NanoES faculty member Arka Majumdar, an assistant professor of electrical and computer engineering and physics, has designed and tested a 3D-printed metamaterial that can manipulate light with nanoscale precision. As they report in a paper published October 4 in the journal Science Advances, their designed optical element focuses light to discrete points in a 3D helical pattern. Designing optical fields in three dimensions could enable creation of ultra-compact depth sensors for self-driving cars, as well as improved components for virtual- or augmented-reality headsets.
