In today’s society, driven by artificial intelligence (AI), the demands for high-performance computing (HPC) in information transmission and processing have become increasingly stringent. However, traditional electronic integrated chips have limited bandwidth when handling massive amounts of information, while also consuming significant space and energy and generating substantial heat. These limitations greatly impact the scalability of HPC and hinder further advancements in AI technology. To address these bottlenecks, we employ state-of-the-art integrated photonics chip technology as a solution, i.e., replacing traditional electron with photon for information transmission and processing. Our integrated photonics chips offer high speed, large bandwidth, low latency, and energy efficiency, meeting the future requirements for high-bandwidth signal interconnects, sensing, and computation. They serve applications in AI, 5G/6G, quantum technology, autonomous driving, low Earth orbit economy, and smart cities.
