Lumentum’s shares have rallied strongly in 2026 alongside peers such as Soitec and Coherent, driven by heightened investor interest in companies supplying optical components for AI data centers. The surge reflects a broader market shift toward firms developing silicon photonics technologies that promise faster, more energy-efficient data transmission.

The company has secured multiyear agreements with Nvidia to co-develop silicon photonics solutions tailored for AI-focused data centers. These deals encompass joint engineering efforts to integrate optical interconnects into next-generation computing infrastructure and include phased milestones tied to performance benchmarks.

Rapid expansion of AI workloads has led hyperscale data-center operators to invest heavily in optical interconnects to manage power and bandwidth challenges. Lumentum’s product pipeline, bolstered by Nvidia collaboration, positions the company to capture a growing share of this high-growth market segment.
