Summary

Story summary

Tower Semiconductor and Scintil Photonics developed first single-chip dense wavelength division multiplexing (DWDM) light engine for AI data centers, enabling signals to share one fiber.
The LEAF Light chip integrates laser arrays and enables data speeds up to 1.6 terabits per second.
Scaling remains a challenge, but production is set to ramp up by 2027, with tens of thousands of units by end of 2026 and broader deployment by 2028.
