silicon photonics technical

"Tower’s advanced silicon photonics platform enables optical networking innovation..."

Silicon photonics is the technology that uses tiny structures etched into silicon chips to generate, control and detect light for moving data and sensing, essentially putting optical fiber functions onto a computer chip. For investors, it matters because it can dramatically increase data speed and energy efficiency in data centers, telecom networks and advanced sensors, potentially lowering costs and enabling new products much like replacing many metal wires with faster, low-power optical highways.

optical circuit switching technical

"...enables nanosecond optical circuit switching and a passive network core..."

Optical circuit switching is a network technique that creates a dedicated path for data by routing light signals end-to-end across fiber optics, like reserving a private highway lane so a convoy can travel without stops or slowdowns. For investors it matters because it can dramatically increase raw bandwidth, lower latency and energy use, and simplify data-center and carrier networks — all factors that affect capital spending, operating costs, and the ability to handle surges in traffic.

transceivers technical

"...optical networking innovation with high-speed optical circuit switching and transceivers for AI infrastructure..."

Transceivers are hardware devices that both send and receive electronic or light-based signals, acting like a two-way mailbox or translator that lets machines talk to each other. For investors they matter because transceivers are essential parts of networks, telecom gear and data centers; changes in demand, supply shortages, price shifts or new technology standards can directly affect manufacturers’ revenues, profit margins and the performance of connected systems.

latency technical

"...designed to deliver low and predictable tail latency with improved resiliency."

Latency is the time delay between when information or an instruction is created and when it is received, processed, or acted on by a market system or data feed. For investors, that delay can alter the price you receive, cause missed trading opportunities, or increase execution risk — like sending a text to buy an item and the seller acting a few seconds later after the price has changed.

network fabric technical

"We are excited to expand our silicon photonics applications beyond traditional data center transceivers and into the network fabric itself..."

A network fabric is the underlying system of hardware and software that routes data between computers, servers and storage so applications can communicate quickly and reliably — think of it as the road network and traffic control for a company’s digital operations. Investors care because a modern, efficient fabric improves performance, lowers operating costs, and makes it easier to scale or add new services, which can affect revenue, margins and risk.

Tower’s advanced silicon photonics platform enables optical networking innovation with high-speed optical circuit switching and transceivers for AI infrastructure

MIGDAL HAEMEK, Israel, and Palo Alto, March 16, 2026 - Tower Semiconductor (NASDAQ/TASE: TSEM), the leading foundry for high-value analog semiconductor solutions, and Oriole Networks, developer of the PRISM (Photonic Routing Infrastructure for Scalable Models) and PRISM Ultra networking platforms, today announced their collaboration to deliver ultra-low, deterministic-latency networking for scale-up and scale-out AI architectures, built on Tower’s mature silicon photonics platform.

As AI models continue to scale, requiring increasingly large clusters of processors, achieving high-radix networks with massive bandwidth and low latency becomes increasingly challenging. Leveraging Tower’s advanced silicon photonics platform, Oriole’s edge-switching architecture enables nanosecond optical circuit switching and a passive network core designed to deliver low and predictable tail latency with improved resiliency. Based on market reports by Dell’Oro and LightCounting, the AI Networking market is expected to surpass $80B by 2030.

Tower Semiconductor’s silicon photonics platform enables the integration of lasers, optical amplification, switching, high-speed modulation, and high-speed detection on a single platform, supporting Oriole’s nanosecond optical circuit switching with fast tunability and high bandwidth for AI networking.

“We are excited to expand our silicon photonics applications beyond traditional data center transceivers and into the network fabric itself,” said Dr. Ed Preisler, General Manager of RF Business Unit at Tower Semiconductor. “Our joint work with Oriole is a key step toward bringing AI back-end networking to market that can scale clusters and break through today’s latency wall.”

The collaboration combines Oriole’s networking technology with Tower’s silicon photonics manufacturing platform to commercialize nanosecond optical circuit switching as a foundational building block of Oriole’s network architecture.

“The exponential growth of AI is forcing the industry to rethink traditional electrical, packet-switched network infrastructure,” said James Regan, CEO of Oriole. “Together with Tower Semiconductor, we’re developing nanosecond optical circuit switching technology designed to deliver a scalable AI fabric where scale-up and scale-out converge into a single, homogeneous, synchronous network. As models grow, legacy architectures hit a hard latency wall - while Oriole’s low, deterministic latency simply steps over it.”

Tower Semiconductor’s high-volume silicon photonics platform is optimized for high-speed optical interconnects and optical circuit switching, making Tower an ideal foundry partner for companies building next-generation AI infrastructure and data center networking.

Both companies will be attending the upcoming OFC 2026 Conference in Los Angeles, March 17–19, with representatives available for meetings during the event.
