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.

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.

Hybrid optics bring color imaging using ultrathin metalenses into focus

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.

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

The ultra-thin semiconductor, which is about 100,000 times thinner than a human hair, stretches across the top of the photonic cavity.

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.
