China has launched a new research laboratory dedicated to photonic computing, a technology that uses light instead of electricity to process information and could help address the growing power demands of artificial intelligence and advanced computing.

The Shanghai Key Laboratory of Integrated Photonic Computing Chips and Systems was officially launched this week in Shanghai. According to local reports, it is China’s first industry-academia platform focused specifically on photonic computing research and development.

The facility is based at Shanghai Jiao Tong University and will bring together researchers and industry partners to develop photonic chips, optical components, computing architectures, and software systems needed to support the technology.

The launch comes as countries and technology companies race to secure enough computing power to train and run increasingly sophisticated AI models. As data centers consume more electricity, researchers are looking beyond traditional semiconductor designs for alternatives that can deliver higher performance with lower energy use.

Light over electrons

Unlike conventional chips that move data using electrons through silicon circuits, photonic chips rely on photons, or particles of light, to transmit and process information.

Because photons travel faster than electrons and generate significantly less heat, photonic systems could potentially offer major gains in speed, bandwidth, and energy efficiency. Researchers believe such systems may help overcome some of the physical limitations facing traditional semiconductor technologies.

Zou Weiwen, director of the new laboratory and a professor at Shanghai Jiao Tong University, highlighted the technology’s potential, describing it as “an important pathway for achieving breakthroughs in computing power, offering advantages in bandwidth, latency, and energy efficiency.”

The new laboratory will focus on several areas, including photonic chip architectures, silicon-photonics integration, optical devices, supporting algorithms, and commercial applications.

China has increasingly identified photonic computing as a strategic technology as it seeks alternatives to advanced semiconductor technologies that remain difficult to access because of export restrictions and supply chain challenges.

Building local ecosystem

Shanghai authorities said they have supported research into photonic computing through multiple science and technology programs while also investing in innovation platforms and industrial development.

The push toward photonic computing comes as researchers worldwide explore alternatives to conventional chip designs that are approaching physical and thermal limits. Supporters of the technology argue that light-based processors could help reduce the massive energy consumption associated with AI data centers while enabling faster data movement across computing systems.

The laboratory is a joint initiative between Shanghai Jiao Tong University and Lightelligence, a Shanghai-based startup specializing in photonic computing technologies.

Lightelligence has previously claimed to be the first company to achieve large-scale deployment of hybrid optical-electronic computing systems. The company has emerged as one of China’s leading players in the photonic computing sector.

Despite growing interest in the technology, significant technical hurdles remain before photonic computing can be deployed at scale.

Zou noted that one major challenge is the lack of a mature software and algorithm ecosystem capable of fully utilizing photonic hardware. Researchers must also address fundamental scientific and engineering problems before the technology can achieve its theoretical performance advantages.

Still, the launch of the new laboratory signals China’s intention to accelerate research into light-based computing as demand for high-performance computing and AI infrastructure continues to grow worldwide.
