Chip war: China claims breakthrough in silicon photonics that could clear technical hurdle
A state-funded semiconductor lab in China said it has achieved a "milestone" in the development of silicon photonics, which could help the country overcome current technical barriers in chip design and achieve self-sufficiency amid US sanctions. JFS Laboratory - based in Wuhan, capital of central Hubei province and a national base for photonics research - was able to light up a laser light source integrated with a silicon-based chip, the first time this was successfully done in China, according
Major players in the global semiconductor industry have devoted resources into advancing silicon photonics, which is believed to hold the future to making better chips for data and graphics processing, as well as artificial intelligence (AI). Its vice-president, Douglas Yu Chen-hua, last year said that a "good silicon photonics integration system" could address critical issues in energy efficiency and computing power in the AI era. EUV machines, required for making advanced chips, are considered the Achilles' heel of the Chinese semiconductor industry, as domestic firms struggle to mass-produce such tools.
