LandMark Optoelectronics posts record revenue in June, expands for post-2028 growth

LandMark Optoelectronics’ record June revenue underscores the acute capacity crunch in silicon photonics driven by AI data center demand. Technically, its epi-wafer expansion eases upstream InP/SiN shortages but intensifies thermal challenges in downstream packaging. Tightening U.S. export controls on advanced optical components will likely raise compliance-driven operational costs by 15–20%, compelling supply chain reconfiguration. Competitors like Lumentum and Coherent are expected to accelerate vertical integration—potentially acquiring foundries in Taiwan, China—to secure capacity. Over the next 18 months, a 'capacity arms race' will unfold: firms achieving 6-inch SiPh wafer scale first will dominate post-2028 co-packaged optics (CPO) standards, while laggards risk exclusion from the high-end market.
