Key Highlights

  • The acquisition enhances Marvell’s optical technology portfolio with plasmonics-based modulation for ultra-fast data transmission.
  • Polariton’s technology supports next-generation coherent and DCI optical interconnects, including ZR and ZR+ applications.
  • The integration aims to deliver higher density, lower energy per bit, and improved scalability for data center architectures.
  • This strategic move addresses the exponential bandwidth growth driven by AI workloads and hyperscale data centers.
  • Marvell continues to invest in advanced optical solutions to maintain leadership in high-speed connectivity for cloud and AI infrastructure.

Marvell is acquiring Polariton Technologies, a developer of high-speed, low-power plasmonics-based silicon photonics devices, shoring up its ability to respond to 3.2T and higher-speed opportunities across scale-across and data center interconnect applications. 

Financial terms of the transaction were not disclosed.

The acquisition strengthens Marvell’s optical technology portfolio by adding advanced modulation capabilities that enable continued scaling in bandwidth, power efficiency, and integration for next-generation coherent and optical interconnect platforms.

As artificial intelligence workloads drive exponential increases in bandwidth demand, data center architectures are evolving to require ever-higher performance optical interconnects, particularly for scale-across and data center interconnect (DCI) applications.

A new optical approach

With hyperscalers’ transition to 1.6T connectivity getting underway, the industry is already advancing toward 3.2T and beyond. Addressing next-generation performance levels requires device-level innovation.

Marvell said Plasmonics offers significant advantages over traditional silicon photonics by enabling higher density, massively parallel optical links with ultra-low energy per bit.

What Polariton brings to the table is its plasmonics-based modulation technology, which is designed to address these challenges in next-generation coherent and DCI optical interconnects, including ZR and ZR+ applications, enabling ultra-fast, energy-efficient optical signaling 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.

“The addition of Polariton extends our optical roadmap with differentiated modulation technology and a highly specialized team,” said Sandeep Bharathi, President, Data Center Group, Marvell. “This investment reflects our commitment to innovation across multiple technology approaches as we continue to build on our leadership in high-speed connectivity.”

Deepening the portfolio

The acquisition further strengthens Marvell’s end-to-end connectivity portfolio across electro-optics, photonics, switching, and custom silicon.

By combining Polariton’s plasmonics technology with Marvell’s existing silicon photonics and DSP capabilities, Marvell said it is well positioned to deliver integrated solutions for next-generation data center architectures, including coherent, scale-across, and DCI optical interconnect platforms.

Bharathi said the acquisition reflects how “Marvell continues to invest in advanced optical technologies to support the rapid evolution of AI and cloud data center infrastructure.”
