What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Choose a silicon photonics platform by first deciding what the link must do: connect servers and racks across a scale-out network, or bring optics close to processors for a higher-density scale-up system. Then compare suppliers on the same evidence: link performance, production maturity, laser and fiber interfaces, package test and serviceability, capacity, and ecosystem fit. Public information shows credible but different approaches; it does not establish one universally superior platform.
Start with the network architecture
Silicon photonics is a photonic integrated-circuit (PIC) technology, not a complete interconnect architecture. The PIC, electrical interface, laser source, package, fiber connection, and deployment model must work together. Decide where the optics belong before comparing PIC platforms.

- Pluggable optics: Modules at the equipment front panel are modular and replaceable, a useful fit when scale-out reach, serviceability, and flexible sourcing matter.
- Near-package optics (NPO): The optical engine sits closer to the processor on the host PCB, shortening the electrical path while retaining a separate optical package.
- Co-packaged optics (CPO): The optical engine is integrated on the same substrate as the processor. This is a more tightly integrated packaging choice, with different implications for assembly, fiber access, and field service.
These distinctions are described in STMicroelectronics’ silicon photonics overview. Neither NPO nor CPO is automatically the right choice simply because a design uses silicon photonics.

Write down the application requirements before contacting suppliers: topology and reach, link count, aggregate and per-lane throughput, bandwidth density, power budget, latency target, allowable service window, and deployment schedule. Those requirements determine whether modularity or tighter integration is more valuable.

Compare maturity using evidence at the right level
Separate production shipments from volume-production statements, demonstrations, announced features, and roadmap targets. Ask for evidence relevant to the planned deployment: process and capacity, qualification status that can be shared, test coverage, known-good-die strategy, and dated roadmap milestones. Supplier statements are useful maturity signals, but the public figures below are not a common independent qualification or yield comparison.
| Supplier and platform evidence | What the public information says | How to interpret it |
|---|---|---|
| Intel | Intel reports cumulative shipments of more than 8 million PICs and over 32 million on-chip lasers in data-center pluggable transceivers. Its product page lists 400 Gb/s, 800 Gb/s, and 1.6 Tb/s solutions, parallel DR and WDM FR interfaces, integrated wafer-scale lasers, and wafer-scale testing. | These are Intel’s own cumulative shipment and capability claims on its product page, not independently normalized cross-vendor results. Ask which product and configuration match the intended link. Intel silicon photonics |
| STMicroelectronics | ST says PIC100 is in volume production, supports up to 100 Gbaud, and serves optical modules from 800 Gb/s to 1.6 Tb/s. ST says it is produced at the 300 mm Crolles foundry in France. PIC200, targeting 200 Gbaud, is under development. | Distinguish the stated PIC100 production status from the PIC200 development target. A baud-rate figure alone does not establish an end-to-end link’s reach, lane count, or performance. ST silicon photonics |
| GlobalFoundries | GF announced SCALE on May 4, 2026, as an OCI-MSA-capable CPO solution. Its release reports native demonstrations of 8λ and 16λ bidirectional DWDM and describes detachable broadband fibers, serviceability, and known-good-die testability. | Treat this as a supplier announcement and demonstrated features, not proof of independent customer qualification, production yield, or broad availability. Ask for deployment-specific qualification and production evidence. GF SCALE announcement |
The figures in this table are not directly comparable measures of performance or maturity: they describe different products, architectures, and kinds of evidence. Request the underlying qualification and production details for the specific offering under consideration.
Normalize the optical and electrical interface
Ask each shortlisted supplier to complete the same interface sheet. Record the values and their conditions rather than comparing headline bandwidth numbers in isolation.

Intel identifies DR and FR examples, while ST describes 200 Gb/s-per-lane PAM4 operation for PIC100-based modules. These descriptions do not by themselves make the offerings like-for-like: lane count, FEC, reach, and operating conditions must match before performance can be compared. Public supplier pages do not provide a complete normalized, end-to-end link-budget comparison across Intel, ST, and GF. For a real design, use the applicable design kit, module specification, and qualification data.
Choose a laser strategy that fits the system
Determine whether the design uses integrated lasers, hybrid or heterogeneous integration, or external or pluggable laser sources. The choice affects thermal placement, optical coupling, package constraints, screening, replacement, and redundancy. Ask how the laser and PIC are tested both individually and in the assembled system, and how a source failure is isolated and handled.
Intel highlights integrated on-die laser arrays and wafer-scale testing; GF describes its CPO solution and testability features. These examples illustrate different implementation evidence, not a universal winner. Evaluate the actual system’s service procedure and source redundancy rather than inferring them from the integration method alone. Intel platform information · GF SCALE announcement

Make fiber coupling and packaging part of platform selection
For NPO and especially CPO, a good PIC is not enough: the fiber-to-chip interface must be manufacturable, testable, and serviceable at the required channel count. Evaluate optical loss alongside alignment tolerance, bandwidth and polarization behavior, assembly yield, fiber-array packaging, connectors, rework, and field access.
Imec notes that lensed-fiber edge coupling can have tight alignment tolerances and require an air gap, complicating high-throughput packaging. Its discussion describes SiN layers and inverse tapers to expand the optical mode, as well as SiN/polymer waveguide approaches for optical redistribution and higher fiber counts. These are technical approaches to assess, not a guarantee that any particular package will meet a system’s yield or cost targets. imec on interfacing silicon photonics for high-density CPO
Corning describes high-channel-count fiber-array units with precise alignment, some designs combining single-mode and polarization-maintaining fibers, micro-optics, and multiple connector assemblies. It also presents CPO FlexConnect single-mode fiber as bend-resilient and optimized for short in-box deployments. When evaluating a fiber solution, ask about connector access, routing and bend constraints, rework, and the module-level service procedure as well as insertion loss. Corning on co-packaged optics

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Check supply, ecosystem, and commercial readiness
Platform selection also depends on whether the whole supply chain can support the design and its operating life. Check process-design-kit access, design support, packaging partners, test availability, capacity commitments, geographic diversification, and the availability of lasers, detectors, fiber, and connectors. Ask for documented capacity and qualification commitments rather than treating a market forecast as evidence that a supplier can meet a particular program’s needs.

TrendForce forecast the combined CPO/NPO market to grow from around US$100 million in 2025 to over US$39 billion by 2030. This is a forecast, not a measure of current deployments or qualification status. ST, attributing figures to LightCounting, says silicon photonics is projected to rise from 43% to 76% of AI-cluster optical technology between 2024 and 2030; that too is a projection, not a measured current share.
