7 terms

co-packaged optics technical

"SCALE™ optical module solution for co-packaged optics (CPO)."

Co-packaged optics are optical components—lasers and fiber interfaces—physically packaged together with a network switch’s main processing chip so light-based data links sit much closer to the chip instead of traveling over long electrical traces. For investors, this matters because it can dramatically cut power use, boost data speed and density, and lower system costs in large data centers and telecom equipment, much like moving a power outlet next to a heavy appliance to avoid long, inefficient extension cords.

silicon photonics technical

"Built with GF’s advanced silicon photonics technology, the SCALE CPO solution"

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.

wavelength-division multiplexing technical

"utilizes both coarse and dense wavelength-division multiplexing (CWDM, DWDM)"

Wavelength-division multiplexing is a fiber-optic technique that sends many separate data streams at once by using different colors (wavelengths) of light on the same glass cable, like adding extra lanes to a highway without building new roads. For investors, it matters because it multiplies network capacity and efficiency, reducing the cost of carrying more traffic and enabling higher-speed services that can drive revenue growth and influence spending on telecom and data-center infrastructure.

CWDM technical

"utilizes both coarse and dense wavelength-division multiplexing (CWDM, DWDM)"

CWDM (Coarse Wavelength Division Multiplexing) is a fiber‑optic technology that lets a single fiber carry multiple separate data streams by using different colors of light, like adding extra lanes to a highway without laying new road. For investors, CWDM matters because it can boost network capacity and cut per‑unit transmission cost with relatively low equipment spending, affecting revenue potential, capital expenditure plans and competitive positioning in telecom and data‑center businesses.

DWDM technical

"utilizes both coarse and dense wavelength-division multiplexing (CWDM, DWDM)"

Dense Wavelength Division Multiplexing (DWDM) is an optical networking technology that lets many separate data streams travel simultaneously over a single fiber by using different colors of light, like adding lanes to a highway without laying new road. For investors, DWDM matters because it enables service providers and data centers to increase capacity, cut per‑unit transmission costs, and delay expensive fiber builds, affecting revenue potential, capital spending and competitive positioning.

through silicon vias technical

"Additional features include through silicon vias (TSVs) for high-speed signaling"

Through silicon vias are tiny vertical electrical connections that pass straight through a slice of semiconductor material to link stacked layers of a microchip, like stairways connecting floors in a building so signals travel shorter, faster routes. For investors, they matter because this packaging technique boosts speed, saves power and increases component density, but also adds manufacturing complexity and capital costs that can affect product competitiveness and profit margins.

silicon interposers technical

"sub-45μm for 2.5D/3D stacking from organic substrates to silicon interposers"

A silicon interposer is a thin slice of silicon used as a high-density connector between tiny chips and their package, carrying many small wiring paths and passive components to link multiple chips closely together. For investors, interposers matter because they enable faster, more power-efficient and compact semiconductor products, influence manufacturing complexity and cost, and can be a strategic advantage for companies making advanced chips or packaging services.

SCALE CPO solution is the industry’s first OCI MSA capable platform and built with GF’s proven silicon photonics technology

MALTA, N.Y., May 04, 2026 (GLOBE NEWSWIRE) -- GlobalFoundries (Nasdaq: GFS) (GF) today announced the introduction of its SCALE™ optical module solution for co-packaged optics (CPO). GF’s SCALE solution, or Silicon photonics Co-packaged Advanced Light Engine solution, is the industry’s first Optical Compute Interconnect Multi-Source Agreement (OCI MSA) capable platform, exceeding the requirements for the OCI MSA’s optical interconnect specification for modern AI scale-up architectures.

Built with GF’s advanced silicon photonics technology, the SCALE CPO solution utilizes both coarse and dense wavelength-division multiplexing (CWDM, DWDM) for bi-directional data transmission over each optical fiber for significant improvements in bandwidth density and system scalability versus traditional copper interconnects. GF has already demonstrated 8λ and 16λ bi-directional DWDM natively on its platform, a fundamental technology milestone that uniquely positions GF to support the industry’s shift to CPO and accelerate the adoption of optical scale-up interconnects. 

GF’s SCALE CPO solution and silicon photonics technology offer an advanced portfolio of fully-qualified photonic devices, such as 50Gbps and 100Gbps micro-ring modulators, coupled ring resonators and integrated photodiodes. Additional features include through silicon vias (TSVs) for high-speed signaling and power delivery and copper pad pitches ranging from 110μm down to sub-45μm for 2.5D/3D stacking from organic substrates to silicon interposers, enabling customers to move quickly from design to volume production. The platform integrates electrical ICs on single-digit advanced nodes, enabling optimization between best-in-class compute and state-of-the-art optics without compromising performance. While GF offers multiple fiber-attach approaches, the SCALE solution leverages broadband detachable fibers with flat insertion loss over the CWDM spectrum to future-proof scaling from 4λ in each direction to 8λ and beyond, while still enabling serviceability and known-good-die testability for next-generation AI interconnects.

“With over a decade of innovation and manufacturing expertise in silicon photonics technology at our disposal, GF stands ready to unlock the future of high-bandwidth, energy-efficient connectivity with our SCALE solution for co-packaged optics,” said Mike Hogan, chief business officer at GF. “Today, our technology already exceeds the requirements set by the OCI MSA, demonstrating our close collaboration with industry leaders and our technology’s readiness to scale next-generation, AI infrastructure.”
