GaN MicroLED Chips Win First Hyperscaler Order
Palomino's optical-link chips for AI data centers are at the commercial-order stage, with scale still unproven.
Updated on Nov. 2, 2026 in Semiconductors
Palomino Laboratories, a California company, has received its first commercial purchase order from a hyperscaler customer for gallium nitride (GaN) MicroLED chips. The agreement includes a statement of work covering development and delivery of specialized MicroLED devices. The technology is at the commercial-order stage; the order does not establish that the chips are ready for deployment at scale.
Why it matters
The order signals that optical interconnect components built from MicroLED technology are moving from research toward a customer's AI infrastructure, a segment where short-distance data links are a growing bottleneck. Palomino's chips are engineered for optical communication rather than the conventional display use of MicroLEDs.
The order is for GaN MicroLED chips designed for high-speed optical communication, with Palomino planning to refine its nanomaterials and chip architecture to improve optical output power and fiber coupling efficiency. The company states its existing technology already meets the customer's other technical specifications, but no measured speed, power, or efficiency figures were released.
The players
Palomino Laboratories
A California company developing gallium nitride MicroLED chips engineered for high-speed optical communication within AI infrastructure.
University of California, Santa Barbara
A research university whose patents are licensed to Palomino Laboratories for its MicroLED optical-communication technology.
The details
MicroLEDs are microscopic light-emitting diodes, semiconductor devices that produce light when electric current passes through them. Palomino's chips use gallium nitride (GaN), a semiconductor material that efficiently emits light at short wavelengths, and are designed to transmit data over short optical fiber links inside AI data centers. The company's technology draws on patents licensed from the University of California, Santa Barbara, and its near-term engineering work focuses on increasing how much light the devices emit and how efficiently that light couples into optical fiber.

The Tech Race
Palomino's MicroLED work is positioned against conventional display MicroLEDs, which target screens rather than the optical links that connect AI computing hardware. The commercial order marks an early step in that repurposing, but the field-level race for AI interconnect components remains at an early stage.
The order does not yet mean the chips are available to users, and no timeline for deployment in AI data centers was announced. Any effect on everyday computing would depend on Palomino proving performance, reliability, and manufacturing capacity first.
The takeaway
Watch whether Palomino publicly reports measured optical output power and fiber coupling efficiency for its GaN MicroLED chips. Those figures would show whether the technology can meet hyperscaler requirements at production volume.
