Marvell Technology has announced the acquisition of Polariton Technologies, a developer of high-speed, low-power plasmonics-based silicon photonics devices, strengthening Marvell's optical technology portfolio with advanced modulation capabilities that enable continued scaling in bandwidth, power efficiency and integration for next-generation coherent and optical interconnect platforms.
As artificial intelligence (AI) workloads drive exponential increases in bandwidth demand, data centre architectures are evolving to require ever-higher performance optical interconnects, particularly for scale-across and data centre interconnect applications. While the transition to 1.6T connectivity is underway, the industry is already advancing toward 3.2T and beyond.
Plasmonics enables higher density, ultra-low energy per bit
Achieving next-generation performance levels requires innovation at the device level. Plasmonics offers significant advantages over traditional silicon photonics by enabling higher density, massively parallel optical links with ultra-low energy per bit, according to Marvell.
Polariton's plasmonics-based modulation technology is designed to address these challenges in next-generation coherent and data centre interconnects (DCI), including ZR and ZR+ applications, enabling ultra-fast, energy-efficient optical signalling in a highly compact form factor. By integrating plasmonics with silicon photonics, the technology extends the performance of optical interconnects and supports the continued scaling of next-generation coherent and optical interconnect solutions.
Investment reflects commitment to multiple technology approaches
Sandeep Bharathi, president of the data centre group at Marvell, says the company continues to invest in advanced optical technologies to support the rapid evolution of AI and cloud data centre infrastructure: "The addition of Polariton extends our optical roadmap with differentiated modulation technology and a highly specialised team. This investment reflects our commitment to innovation across multiple technology approaches as we continue to build on our leadership in high-speed connectivity."
Polariton brings a team with deep expertise in plasmonics, silicon photonics and high-speed optical modulation. The addition of this engineering talent enhances Marvell's capabilities in advanced photonics and supports ongoing development of next-generation optical platforms.
End-to-end connectivity portfolio strengthened
The acquisition follows a string of strategic moves by Marvell to dominate the photonics stack, including the recent acquisition of Celestial AI. Polariton brings deep expertise in high-speed optical modulation and plasmonics, enhancing Marvell's ability to develop custom silicon and electro-optics for the most demanding AI infrastructures.
Financial terms of the transaction were not disclosed, but the deal positions Marvell as a primary architect of the "all-optical" data centre transition.
