Researchers at Caltech have developed a groundbreaking technology that “evolves” optical devices and fabricates them using a specialized 3D printer. These devices, composed of optical metamaterials, gain their unique properties from nanometer-scale structures. This innovation could enable cameras and sensors to detect and manipulate light in ways previously impossible at such small scales.
The research was conducted in the lab of Andrei Faraon, the William L. Valentine Professor of Applied Physics and Electrical Engineering and was published in the journal Nature Communications.
While Faraon has worked with optical metamaterials before, this marks the first time the materials have been adapted into fully three-dimensional structures.
