Odaily Planet Daily report: "White-Haired God of Stocks" Serenity posted that Michael Hurlston, CEO of Lumentum, has warned that the supply chain for indium phosphide (InP) lasers targeting AI data centers is facing a more severe shortage than that of memory chips. Even with Lumentum’s five InP wafer fabs, shipment volumes 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 noted that current supply pressure is primarily concentrated in the EML (electro-absorption modulated laser) segment, but the shortage of InP lasers could also continue to spread. The company remains long-term bullish on "bottleneck investment" opportunities within the optical communication laser supply chain, with focus on related companies including Applied Optoelectronics (AAOI), Sivers Semiconductors (SIVE), Lumentum (LITE), and Coherent (COHR). As capital expenditures for AI data centers continue to rise, previously undervalued infrastructure components such as optical modules and lasers are undergoing repricing, and the supply bottleneck of InP lasers may become a critical constraint in the expansion of AI computing power.
