A major technological breakthrough: China has successfully developed a new photonic chip
Recently, Researcher Zhang Junwen and Professor Chi Nan from the School of Information Science and Engineering at Fudan University have collaborated with relevant research teams
to introduce multi-dimensional multiplexing technology into on-chip optical interconnect architecture through precise design and optimization. This not only significantly improves the data transmission throughput, but also excels in power consumption and latency. It has strong scalability and compatibility, and is suitable for a variety of high-performance computing scenarios.
On this basis, the team designed and developed a silicon photonic integrated high-order mode multiplexer chip, which achieved ultra-large capacity on-chip optical data transmission. Experimental results show that
the chip can support a data transmission speed of 38Tb per second, which means that in the future, 4.75 trillion parameters of a large model can be transferred in 1 second, which significantly improves the communication performance and reliability between large model training and computing clusters , and provides strong support for applications such as artificial intelligence, large model training, and GPU accelerated computing.
This technological breakthrough not only provides a new solution for optical interconnection systems in data centers and high-performance computing servers, but also lays a solid technical foundation for artificial intelligence, large-scale parallel computing and large model training. The relevant research results were published in the international journal Nature Communications.
