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.
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.
Engineers at the University of Washington have for the first time developed a method to safely charge a smartphone wirelessly using a laser.
Five faculty members at the University of Washington have been awarded early-career fellowships from the Alfred P. Sloan Foundation. The new Sloan Fellows, announced Feb. 15, include Maya Cakmak, assistant professor of computer science and engineering; Jiun-Haw Chu, assistant professor of clean energy and physics; Arka Majumdar, assistant professor of electrical engineering and physics; Jessica Werk, assistant professor of astronomy; and Chelsea Wood, assistant professor of aquatic and fishery sciences.
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.
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.
