New metasurface design can control optical fields in three dimensions
A team led by scientists at the University of Washington has designed and tested a 3D-printed metamaterial that can manipulate light with nanoscale precision. As they report in a paper published Oct. 4 in the journal Science Advances, their designed optical element focuses light to discrete points in a 3D helical pattern.

Scientists engineer a functional optical lens out of 2D materials
In a paper published Oct. 8 in the journal Nano Letters, a team from the University of Washington and the National Tsing Hua University in Taiwan announced that it has constructed functional metalenses that are one-tenth to one-half the thickness of the wavelengths of light that they focus. Their metalenses, which were constructed out of layered 2D materials, were as thin as 190 nanometers — less than 1/100,000ths of an inch thick.

Hybrid optics bring color imaging using ultrathin metalenses into focus
In a paper published Feb. 9 in Science Advances, scientists at the University of Washington announced that they have successfully combined two different imaging methods — a type of lens designed for nanoscale interaction with lightwaves, along with robust computational processing — to create full-color images.

UW scientists build a nanolaser using a single atomic sheet
University of Washington scientists have built a new nanometer-sized laser using a semiconductor that’s only three atoms thick. It could help open the door to next-generation computing that uses light, rather than electrons, to transfer information.
