In the intelligent era, computing power stands as the cornerstone and driving force, while vision remains the primary means by which humans and machines perceive the world. Amidst the rise of artificial intelligence, the 'sensing-computing integrated chip' emerges as a fundamental component, endowing miniaturized and portable devices such as smartphones, robots, and drones with robust sensing and computing capabilities. The Cui Kaiyu research group, led by Professor Huang Yidong from the Department of Electronics at Tsinghua University, has introduced the world's first 'Spectral Chip' - Spectral Imaging Chip 2.0. This innovative chip is tailored for complex visual tasks and represents the pioneering optical computing chip capable of directly utilizing natural light infused with spectral information as input. It overcomes the significant hurdles that have hindered the practical application of existing optical neural networks.
