Foreign media: The Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences has developed the world's first ultra-high parallel photonic computing chip, with a theoretical performance of 2560 trillion operations per second (TOPS), running at a clock speed of 50GHz.
According to the journal "eLight", this chip uses more than 100 different wavelength optical channels, similar to upgrading a single lane to a hundred-lane highway, causing a surge in data throughput while maintaining the same chip size and clock speed. The core technology is the micro-ring resonator, which splits lasers into independent data streams, with a bandwidth exceeding 40nm, low insertion loss, supporting applications from image recognition to real-time signal processing.
Photonic transmission avoids resistive heat loss in electronic circuits, making it suitable for low-latency scenarios such as AI neural networks and drone swarms. Meanwhile, Shanghai Jiao Tong University's CHIPX has launched China's first thin-film lithium niobate photonic chip pilot line, with an annual production capacity of 12,000 wafers and a modulation bandwidth exceeding 110GHz. These two breakthroughs respectively promote parallel photonic computing and the mass production of photonic devices, accelerating the development of China's photonics technology.
