New research from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) paves the way to smaller and more efficient components for telecommunications, quantum communication, and other photonic technologies.
The work, from the lab of Professor Federico Capasso, the Robert L. Wallace Professor of Applied Physics and Vinton Hayes Senior Research Fellow in Electrical Engineering, combines layered engineered semiconductor materials with special nanostructured devices called metasurfaces, creating a unique semiconductor device that exhibits an extraordinarily strong ability to mix and transform different colors of light, including at near-infrared wavelengths that exist in the technologically valuable range of fiber-optic networks.
The research, a collaboration between Harvard SEAS, University of Texas Austin and the University of California, Irvine, was published in Nature Nanotechnology.
