Serenity: AI Data Center InP Laser Supply Gap May Exceed Memory Chips, Highlighting the Value of Optical Communication Bottlenecks

The "White-Haired Stock God" Serenity stated in an article that Lumentum CEO Michael Hurlston has issued a warning that the supply chain for indium phosphide (InP) lasers used in AI data centers is facing a more severe shortage than memory chips. Even with Lumentum's five InP wafer fabs, product shipments may still fall more than 30% short of customer demand, indicating that the expansion of AI infrastructure is encountering a critical bottleneck in optical communication components. Serenity pointed out that the current supply pressure is mainly concentrated in the EML (Electro-Absorption Modulated Laser) sector, but the shortage of InP lasers may also continue to spread.
