JDSU split in two — Lumentum took the lasers and became an AI-optics supplier

Lumentum became an independent company on 1 August 2015 when JDS Uniphase separated its Communications and Commercial Optical Products business.

The new company inherited optical components for telecommunications and data networks alongside commercial laser technology used in manufacturing and other applications.

What followed was not a straight expansion into every adjacent market. Lumentum moved through specific technical and commercial turning points that gradually changed what customers expected from it.

A focused spin-off gave optical communications its own capital strategy

Lumentum began trading on Nasdaq in August 2015 under the LITE ticker. The separation allowed management to concentrate investment on communications optics and lasers rather than the broader JDSU portfolio.

For Lumentum, access to public markets was more than a branding milestone. It increased financial transparency and created another route to fund expansion, acquisitions or long-term product development.

VCSELs connected optical technology to consumer 3D sensing

Lumentum moved vertical-cavity surface-emitting laser technology into high-volume consumer applications, including depth sensing and facial-recognition systems.

This was an important turning point because it expanded what Lumentum could offer or the markets it could address. The effect becomes clearer when viewed as part of the longer sequence of changes that followed.

Oclaro broadened the high-speed communications portfolio

Lumentum acquired Oclaro in 2018, adding optical components and technologies for high-speed telecom and data-centre links.

The transaction mattered because it changed the shape of Lumentum rather than simply adding revenue. It brought additional technology, customers, geographic reach or operating capability into the group and influenced the next stage of its strategy.

AI data centres made optical bandwidth the new bottleneck

As cloud operators build larger AI clusters, the amount of data moving between servers and switches has increased sharply. Lumentum’s lasers and optical components therefore sit inside a market increasingly driven by 400G, 800G and higher-speed connectivity.

This shift also changed how customers consumed the technology. Instead of treating software or infrastructure as a one-off purchase, the relationship became more continuous, with updates, capacity and services delivered over time.

The optical spin-off found a new growth engine in AI

As of 18 September 2026, lumentum now serves cloud, telecom and industrial markets with optical and laser technologies. Its history as a spin-off is important because the company’s modern AI exposure comes from the same photonics expertise that originally served long-distance communications.

For readers following the brand today, the history explains why newer announcements often connect back to technology or business decisions made much earlier.
