Photonics Chip Developer Guangyin Technology Raises RMB 100 Million in Pre-A Round

Guangyin Technology, a developer of silicon-based photonic integrated chips, has completed a RMB 100 million (about $14 million) Pre-A financing round, with investors including the Photonics Strong-Chain Fund, Shanda Investment, YOFC Fund, Luoyang Yingcai, CAS Star, and Xi'an Caijin, according to 36Kr. The company said the proceeds will be used mainly to build a new laboratory in Shanghai, recruit talent, and advance mass production. Founded in 2021 in Xuzhou, Guangyin Technology develops miniaturized spectral sensing modules based on a "computational spectrometer" approach that encodes incident light on-chip and reconstructs full spectral information via algorithms. The company said its spectral chip covers wavelengths of 600-2500 nm, with resolution up to 0.01 nm, and targets a mass-production cost below $20. The company said its main customers include Huawei and Xiaomi, and it is also working with liquor makers to monitor fermentation indicators using spectral sensors.
