Samsung Reportedly Acquires Four U.S. Silicon Photonics Patents From Rockley as It Advances Optical Interconnects

Samsung Electronics has reportedly picked up four U.S. patents related to silicon photonics from UK firm Rockley Photonics, according to a Nov. 11 report by South Korean outlet Shinailbo. The publication said the transfer took place in September 2026 and cited records from the U.S. Patent and Trademark Office (USPTO).

The reported acquisition lands as Samsung steps up public demonstrations of optical interconnect technology aimed at next-generation computing systems. At SEDEX 2026, Samsung Electronics presented a demonstration of a co-packaged optics (CPO) optical interconnect—an approach that brings optical components closer to, or directly alongside, switching or compute silicon to reduce the power and bandwidth bottlenecks associated with traditional electrical interconnects.

Silicon photonics—the use of silicon-based processes to build optical components—has become a focal point for major chip and systems companies seeking higher bandwidth and improved energy efficiency in data centers and AI infrastructure. Moving data between chips and across racks is increasingly a limiting factor for performance and operating cost, and optical links are widely seen as one of the most viable routes to scaling bandwidth without proportionally increasing power.

While the Shinailbo report did not detail the financial terms of the transaction, it pointed to USPTO documentation indicating that Rockley Photonics assigned four U.S. patents to Samsung Electronics. Rockley has been known for developing silicon-photonic technologies, and patent transfers like this can signal strategic positioning as larger firms seek to consolidate key intellectual property ahead of product development or commercialization.

The timing also underscores how intellectual property is becoming a competitive lever as the industry explores CPO and other high-density optical interconnect architectures. Demonstrations at events such as SEDEX are often used to show readiness and attract ecosystem partners, but bringing these systems into volume deployment typically requires control over a wide range of packaging, optics, and device-level know-how—areas where patents can play an outsized role.

For Samsung, the combination of a public CPO showcase and a reported patent purchase suggests continued investment in technologies intended to support higher-throughput computing platforms, even as the broader market works through standardization, manufacturability, and reliability challenges tied to integrating optics with advanced semiconductor packaging.

Why it matters

Optical interconnects are increasingly critical for AI training and cloud data centers, where moving data can consume as much attention as compute performance. If Samsung is accumulating silicon photonics IP while demonstrating CPO, it could strengthen its position in future high-bandwidth networking and packaging ecosystems. The next signals to watch are whether Samsung expands partnerships, discloses product roadmaps, or shows additional prototypes moving beyond demos toward deployable hardware.
