Guoke Photonics Raises Hundreds of Millions in Series B+

This funding round signals sustained capital appetite for silicon photonics, a key enabler for AI data center interconnectivity. The participation of regional state-backed investors, from Sichuan, Hangzhou, and Shandong, suggests strategic interest beyond pure financial returns, likely tied to local tech supply chains. For the sector, the focus on overseas delivery centers indicates that Chinese photonics firms are positioning for global AI infrastructure demand, despite export control headwinds. The open question is whether this capital can translate into production scale and customer wins that justify the valuation momentum.
