Coherent Breaks Ground on Expanded Texas Facility, Scaling AI’s Optical Backbone
TL;DR
Coherent broke ground on June 16, 2026, on an expanded manufacturing building in Sherman, Texas. The site is meant to scale what Coherent calls the first volume-production 6-inch indium phosphide fab. The parts are not GPUs, but they keep AI clusters connected: lasers, transceivers, optical modules and networking components that move data between chips, racks and data centers.
Nauti's Take
The useful part of this story is not the ceremony language, but the materials bottleneck. AI looks like software from the outside, yet it consumes factories, specialty wafers, lasers and power budgets.
Coherent is expanding at the layer many AI debates skip: how data moves from A to B fast enough without the network becoming the next hard limit. The announcement is PR-heavy, but the strategic direction makes sense.
Briefingshow
AI infrastructure is constrained by more than GPU supply. Large clusters need fast, power-efficient links because copper becomes expensive and inefficient across rack and data-center distances. If 6-inch InP wafers produce more optical parts per run, they can reduce cost and pressure in photonics supply.
For operators, the real question is whether networking scales as quickly as compute.
