The article says AI optics supply is constrained by China-controlled export licensing for indium-phosphide wafers used in data-center lasers. Lumentum (LITE) agreed to pay AXT (AXTI) $87M for six years of wafer supply, but AXT’s shipments depend on permits from Beijing’s Ministry of Commerce. It cites Reuters on possible FCC rules limiting Chinese optical transceivers and notes large stock swings for LITE, COHR, and AAOI.
