July 5, 2026, 10:08 PM EDT. Nvidia CEO Jensen Huang warned that photonics tech-key for using light to move data in AI-has become a bottleneck. Nvidia has put $2 billion into both Coherent and Lumentum Holdings, two names in the photonics and optical networking space. Coherent, now in the S&P 500, posted a 27% jump in revenue to $1.8 billion and shares have doubled this year. But it leans hard on data center demand. Lumentum saw revenue nearly double to $808 million last quarter and is up 130% for the year. Still, it's up against tough rivals and trades at a high price. Nokia, also getting Nvidia money, may get a lift as AI demand rises. All three are looking to tackle tough data transfer problems as AI ramps up.
