Coherent Receives $50 Million Preliminary Funding Commitment Under U.S. CHIPS Act
Miles Bennett
Optical-chip maker Coherent signed a preliminary agreement with the U.S. Commerce Department for $50 million in CHIPS Act funding to expand its indium-phosphide fab — a targeted bet on the AI data-center optical-interconnect supply chain, though the money has not yet formally landed.
What is the money for?
Coherent will use the $50 million to expand its 6-inch indium-phosphide wafer fab in Sherman, Texas.
Indium phosphide — a semiconductor material that converts electrical signals into light — is the core ingredient for optical transceivers. This means → the funding targets the light pipes that connect chips, not chip fabrication itself.
Once complete, the facility's manufacturing footprint will double, wafer capacity will quadruple to 4× current levels, and the project is expected to add over 1,000 jobs, including more than 550 in advanced manufacturing and engineering.
Why photonic chips?
Inside AI data centers, GPUs, memory, and switches must move massive volumes of data between each other. Traditional electrical signaling is hitting bandwidth and power walls. In plain terms = no matter how fast the chip computes, the whole system stalls if data can't move.
Optical transceivers — devices that carry data on light instead of electrons — are becoming the bottleneck component in AI infrastructure. Whoever can build more, faster optical devices holds the chokepoint of AI scale-out.
Coherent CEO Jim Anderson put it directly: "Semiconductor photonic devices are the core building blocks of AI infrastructure." This reflects a shift — optical interconnect has moved from an optional upgrade to a required utility.
Has the money actually landed?
Not yet. What was signed is a preliminary memorandum, not a formal funding agreement. This means → further Commerce Department review is required, and the final amount and terms could still change.
On the day of the announcement, Coherent shares fell 3.30%. In plain terms = the market does not pay up for an uncashed check; short-term sentiment moved faster than the policy signal.
From a supply-chain view, however, continued CHIPS Act funding flowing into photonic materials signals that Washington sees optical interconnect as a link in AI infrastructure that must be secured on U.S. soil.
