China’s Wuxi Photonic Chip Joint Research Center—formally known as the Chip Hub for Integrated Photonics Xplore (CHIPX) and affiliated with Shanghai Jiao Tong University—has commenced production of 6-inch lithium niobate (LiNbO₃) thin-film photonic chips. This marks a significant advance in China’s efforts to overcome US-imposed tech restrictions and strengthen its semiconductor and quantum computing capabilities.
