Marvell Technology, a leading semiconductor provider for data centers, has announced its acquisition of Swiss startup Polariton Technologies. The financial details of the deal have not been disclosed. Polariton is known for developing high-speed and energy-efficient devices based on plasmonic silicon photonics, technology that promises high integration density and ultra-low energy consumption per bit.
This acquisition is timely as artificial intelligence continues to drive exponential growth in bandwidth demands. Data center architectures are evolving towards more efficient optical interconnections, particularly for scaling and inter-data center connectivity. While the industry is transitioning to 1.6 Tbps speeds, it is already eyeing advancements toward 3.2 Tbps and beyond. Marvell believes that integrating Polariton's expertise will bolster its portfolio in advanced optical technologies.
According to Sandeep Bharathi, president of Marvell's data center division, this acquisition expands the company's optical roadmap with differentiated modulation technology and a highly skilled team. Polariton's knowledge in plasmonics, silicon photonics, and high-speed optical modulation enhances Marvell's capabilities in electro-optics, photonics, switching, and specialized chips.
The acquisition of Polariton marks Marvell's third major deal aimed at strengthening its position in AI connectivity within just a few months. In December 2025, Marvell announced a $3.25 billion acquisition of Celestial AI, gaining access to breakthrough "Photonic Fabric" technology that enables data transmission via light at the packet, system, and rack levels. This technology provides double the energy efficiency and tenfold bandwidth compared to copper connections, facilitating data rates of up to 16 terabits per second on a single chiplet.
Less than a month later, in January 2026, Marvell acquired XConn Technologies for approximately $540 million, a company that specializes in advanced PCIe and CXL switches crucial for high-performance computing systems. This acquisition expanded Marvell's portfolio in high-speed electrical connections and strengthened its position in developing switches for the new UALink industry standard.
With Polariton now on board, Marvell aims to combine plasmonic technology with silicon photonics, addressing critical scalability challenges with optical solutions, while XConn enhances its electrical connection capabilities. This strategic combination positions Marvell to create a comprehensive connectivity platform for data centers, offering both optical and electrical solutions to meet the demands of next-generation AI systems. The company anticipates significant financial returns from these acquisitions, projecting around $100 million in revenue from XConn by the 2028 fiscal year and $1 billion annually from Celestial AI by the end of the 2029 fiscal year.
This strategic move underscores Marvell's commitment to leading the charge in the rapidly evolving data center market, positioning itself ahead of competitors.
