Revolutionary 'LEGO-Like' Photonic Chip Paves Way For Semiconductor Breakthroughs (scitechdaily.com) 7
"Researchers at the University of Sydney Nano Institute have developed a small silicon semiconductor chip that combines electronic and photonic (light-based) elements," reports SciTechDaily.
"This innovation greatly enhances radio-frequency (RF) bandwidth and the ability to accurately control information flowing through the unit." Expanded bandwidth means more information can flow through the chip and the inclusion of photonics allows for advanced filter controls, creating a versatile new semiconductor device. Researchers expect the chip will have applications in advanced radar, satellite systems, wireless networks, and the roll-out of 6G and 7G telecommunications and also open the door to advanced sovereign manufacturing. It could also assist in the creation of high-tech value-add factories at places like Western Sydney's Aerotropolis precinct.
The chip is built using an emerging technology in silicon photonics that allows the integration of diverse systems on semiconductors less than 5 millimeters wide. Pro-Vice-Chancellor (Research) Professor Ben Eggleton, who guides the research team, likened it to fitting together Lego building blocks, where new materials are integrated through advanced packaging of components, using electronic 'chiplets'.... Dr Alvaro Casas Bedoya, Associate Director for Photonic Integration in the School of Physics, who led the chip design, said the unique method of heterogeneous materials integration has been 10 years in the making. "The combined use of overseas semiconductor foundries to make the basic chip wafer with local research infrastructure and manufacturing has been vital in developing this photonic integrated circuit," he said. "This architecture means Australia could develop its own sovereign chip manufacturing without exclusively relying on international foundries for the value-add process...."
The photonic circuit in the chip means a device with an impressive 15 gigahertz bandwidth of tunable frequencies with spectral resolution down to just 37 megahertz, which is less than a quarter of one percent of the total bandwidth.
