Research Team Develops New Way To Make Integrated Photonics

The signals from a lighthouse to ships at sea is an early example of optical communication, the use of light to transmit information. Today, researchers in the field of integrated photonics are using optical communications principles to build high-tech devices, like lightning-fast computers, which utilize light instead of electricity.


At the University of Delaware, a research team led by Tingyi Gu, assistant professor of electrical and computer engineering, has designed an integrated photonics platform with a one-dimensional metalens—a thin lens that can be designed at the nanoscale to focus light in a specific way—and metasurfaces—tiny surfaces made with nanostructures to manipulate the transmitted or reflected light— that limit the loss of information. The team recently described their device in the journal Nature Communications.
