The lab, based at Shanghai Jiao Tong University, will focus on developing photonic chips that use light particles for data transmission and computation, offering potential advantages in speed and energy efficiency for powering AI models.", "body_md": "# Facing US chip curbs, China launches photonics lab to power AI with light\n\nLab director says fundamental scientific challenges need to be overcome to achieve theoretical performance\n\n[Ben Jiang](/author/ben-jiang)in Beijing\n\n[US technology curbs](https://www.scmp.com/tech/tech-trends/article/3355294/beyond-nvidia-how-us-export-curbs-are-forcing-china-redesign-its-ai-chip-industry?module=inline&pgtype=article)hobbling its ambitions in artificial intelligence development.\n\nThe Shanghai Key Laboratory of Integrated Photonic Computing Chips and Systems, launched on Wednesday, was China’s first industry-academia platform dedicated to the field, Shanghai’s Jiefang Daily reported on Thursday.\n\nZou Weiwen, director of the new laboratory and a photonics professor at Shanghai Jiao Tong University, said photonic – or optical – computing was “an important pathway for achieving breakthroughs in computing power, offering advantages in bandwidth, latency, and energy efficiency”. The new lab is based at the university.\n\nWhile traditional semiconductors rely on electrons to push data through silicon circuits, photonic chips use light particles – photons – for data transmission and computation.\n\nBecause photons travel much faster than electrons and generate less heat, photonic chips could deliver higher performance while consuming just a fraction of the power – making them a potential alternative to the conventional semiconductors used in the power-hungry data centres supporting the AI boom.\n\nThe Shanghai lab would focus on research into photonic chip architectures, silicon-photonics integration, optical components and the algorithms and commercial applications needed to make them viable, Jiefang Daily reported.\n\nThe launch comes as tech companies around the world race to secure the massive computing power required to train and run increasingly sophisticated AI models. The surging energy consumption and performance demands of the models are pushing conventional silicon semiconductors to their physical limits.", "url": "https://wpnews.pro/news/facing-us-chip-curbs-china-launches-photonics-lab-to-power-ai-with-light", "canonical_source": "https://www.scmp.com/tech/tech-war/article/3356901/facing-us-chip-curbs-china-launches-photonics-lab-power-ai-light", "published_at": "2026-06-12 11:43:06+00:00", "updated_at": "2026-06-12 11:50:32.492135+00:00", "lang": "en", "topics": ["ai-chips", "ai-research", "ai-infrastructure", "artificial-intelligence"], "entities": ["Shanghai Key Laboratory of Integrated Photonic Computing Chips and Systems", "Zou Weiwen", "Shanghai Jiao Tong University", "Jiefang Daily", "Ben Jiang"], "alternates": {"html": "https://wpnews.pro/news/facing-us-chip-curbs-china-launches-photonics-lab-to-power-ai-with-light", "markdown": "https://wpnews.pro/news/facing-us-chip-curbs-china-launches-photonics-lab-to-power-ai-with-light.md", "text": "https://wpnews.pro/news/facing-us-chip-curbs-china-launches-photonics-lab-to-power-ai-with-light.txt", "jsonld": "https://wpnews.pro/news/facing-us-chip-curbs-china-launches-photonics-lab-to-power-ai-with-light.jsonld"}}
