A first-of-its-kind chip architecture that uses both electronic- and light-based components could pave the way for 6G technology.
The research, published Nov. 20 in Nature Communications, offers a blueprint for communications chips needed for advanced radar, satellite systems, advanced wireless networks (Wi-Fi), and even future generations of 6G and 7G mobile technology.
By integrating light-based, or photonic components, into a conventional electronic-based circuit board, researchers dramatically increased radio frequency (RF) bandwidth, while demonstrating improved signal accuracy at high frequencies.
They built a working prototype of the networking semiconductor chip, measuring 0.2 by 0.2 inches (5 by 5 millimeters), by sourcing a silicon wafer and attaching the electronic and photonics components — in the form of “chiplets” — like Lego bricks.
