Coherent scaling InP semiconductor capacity to meet AI datacenter demand; doubling output by year-end, then 2x+ again in 2027.
“On track to double internal InP output by year‑end and more than double again by 2027... 6‑inch platform producing EMLs, CW lasers, and photodiodes, with higher yields than 3‑inch lines”
Why it matters
Coherent is declaring a critical capacity constraint in indium phosphide (InP) semiconductors for optical transceivers—the backbone of AI datacenter interconnect. The aggressive 4x+ expansion over 18 months signals severe supply-demand imbalance and validates the bottleneck thesis.
Investment implication
Suppliers of InP precursors, wafer manufacturing equipment, and thermal solutions stand to benefit materially. Competitors without comparable capacity expansion may lose share in the high-growth datacenter optical segment.
