Researchers at Fudan University Claim Breakthrough in Light-Based Chips

In a significant development, Chinese researchers at Fudan University have made a major breakthrough in the creation of silicon photonic multiplexer chips, which utilize light instead of electricity for communication. This innovation has the potential to revolutionize the way data is transmitted and could be a crucial step towards the widespread adoption of photonics-based chips.

According to reports from the Global Times, a state-run tabloid, the silicon photonic multiplexer chip is capable of transferring an astonishing 4.75 trillion parameters per second, making it one of the fastest data transmission devices in the world. The chip employs a technique known as high-order mode multiplexing, which enables it to transmit multiple inputs through a single output, resulting in a highly efficient and powerful device.

The development of this chip marks a significant milestone in the transition from electronic to optical transmission. As Ma Jihua, a telecom industry insider, noted, “Research into photonic chips has gained momentum, facilitating the shift from electronic to optical transmission.” This shift is expected to have a profound impact on the way data is transmitted and processed, with photonics-based chips offering higher speeds and lower energy consumption compared to traditional electronic devices.

One of the key advantages of the new chip is its ability to bridge the gap between photonic and electronic languages. This allows it to interconnect light-based data transmission with traditional CMOS technology, making it a highly versatile and powerful device.

The development of this chip is also significant because it highlights China’s growing investment in photonics research. China’s research institutions are currently producing more than double the amount of research output on post-Moore’s Law chip technologies compared to the US, and representing the lion’s share of top-cited research. This has led to concerns that China may overtake the US in the development of photonics-based chips in the long run.

While the development of this chip is a significant breakthrough, it is worth noting that the Global Times has a history of spreading misinformation and fabrications. However, the fact that Fudan University has allegedly submitted its findings to Nature, the world’s most respected scientific journal, for review adds credibility to the claims.

The implications of this breakthrough are far-reaching, with photonics-based chips offering a major paradigm shift in computer design. The use of light to transmit data is already being explored in the enterprise space, with companies like Nvidia and AMD investing heavily in photonics-based network switches. The development of this chip could accelerate this trend and lead to a major shift in the way data is transmitted and processed.
