Emerging Photonics in AI: The Rise of Lightstandard
A major stride in computing technology has been achieved with a considerable investment secured by Lightstandard, an innovative Chinese startup specializing in photonic chip research and development. Having raised nearly one billion yuan (around 21 billion yen), the company, backed by key investors including Zhongying Capital, showcases the growing confidence in the potential of photonics within technological advancements. Step Venture Capital and RollStone Capital, along with previous shareholders, contributed to this endorsement of Lightstandard’s ambitious project.
Lightstandard is comprised of a team of experts originating from prestigious institutions such as Oxford University, Fudan University, and the University of Chicago. This pool of talent is not only adept in optical communication and computer chip technologies but is also actively engaged in enhancing large language models (LLM) of artificial intelligence (AI) through the development of photonic chips. These chips are intrinsically different from traditional ones, as they process information using light signals rather than electrical signals, leading to faster transmission speeds, reduced power consumption, and broader bandwidth capabilities.
With applications spanning communication, sensing, and computing, photonic chips herald a transformative era in technology due to their potential for massively parallel computing capabilities through multiple wavelengths of light. Co-founder Xiong Yinxing acknowledges that while the photonic chip technology is already operational to some extent in communications, there are ongoing challenges and developments in computing and sensing fields, such as the advancement of LiDAR technologies based on FMCW (Frequency-Modulated Continuous Wave) techniques.
The advent of AI has precipitated a massive demand for computational power that photonic chips are poised to fulfill. According to Xiong’s estimates, these chips could realize computational capabilities that are over a hundred times greater than conventional chips, while drastically reducing power consumption and latency. This breakthrough is particularly significant as it also aligns with the diminishing returns of Moore’s Law, offering an alternative to the semiconductor exposure equipment heavily relied upon by traditional integrated circuits.
As AI and the need for high-performance LLM chips grow, photonic chips like those developed by Lightstandard, which employ a PCM (Phase Change Memory) + Crossbar approach, stand ready to deliver heightened integration and energy efficiency. The company has already made significant headway in refining its OPU (Optical Processing Unit) chip, completing three rounds of tape-out improvements.
Lightstandard’s success marks a promising venture in China’s quest for domestic chip production, boasting of technical prowess comparable with international standards, mature chip design software, and factories. The sheer volume and quality of data required by generative AI models underscore the escalating demand for chips with high computational ability, low power consumption, and efficient cost-performance, a demand that photonic chips are set to meet.
