Choose a silicon photonics platform by first deciding where the optics will sit and what the link must do. Pluggable transceivers generally suit modular scale-out connections; near-package optics (NPO) and co-packaged optics (CPO) move optical engines closer to compute to reduce electrical distance and increase density, while tightening packaging and service constraints. Then compare suppliers on production evidence, link performance, laser strategy, fiber interface, testability, serviceability, capacity, and ecosystem fit. Public information shows credible but different approaches—not one universally superior platform.
Start with the network architecture and deployment constraints
“Silicon photonics platform” can refer to a photonic integrated circuit (PIC), its process and design environment, the optical engine and laser, or the packaged system that connects to fibers and host electronics. These choices must work together, but they are not the same decision.
Write down the requirements for the actual deployment before comparing suppliers:
- Topology and reach: for example, links among servers and racks or links between tightly integrated compute resources.
- Number of links, aggregate throughput, per-lane rate, and required bandwidth density.
- Power and thermal budgets, latency targets, and the electrical host interface.
- Allowable maintenance window, component replacement expectations, and deployment date.
- Required fiber type, connector access, and the conditions in which the equipment will operate.
ST describes pluggables as a modular, flexible fit for scale-out, NPO as an optical engine closer to the processor on the host PCB, and CPO as an engine integrated on the same substrate as the processor. These placements create different trade-offs: moving optics closer can shorten electrical paths and support higher density, but can make packaging, repair, and system qualification more demanding. ST’s architecture overview explains these distinctions.

Do not treat “silicon photonics” itself as the architecture choice. The PIC process, electrical interface, laser source, package, fiber connection, and service model all need compatible specifications.
Separate demonstrated production from roadmaps and announcements
Ask each supplier for evidence at the scale relevant to your deployment: present production status, available capacity, process controls, qualification status that can be shared, test coverage, known-good-die strategy, and roadmap dates. Distinguish shipped products from demonstrations, announced capabilities, and future targets.
| Supplier | Publicly stated evidence | What the evidence establishes—and does not |
|---|---|---|
| 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 platform and shipment claims. They are useful evidence of deployment and product range, not an independent comparison of supplier yield, cost, or qualification. |
| 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 PIC100 is produced at its 300 mm Crolles foundry in France. PIC200, targeting 200 Gbaud, is under development. | The page gives ST’s stated production status, process location, and product roadmap. PIC200 is a development target, not a currently established production capability. |
| GlobalFoundries | In a May 4, 2026 announcement, GF described SCALE as an OCI-MSA-capable CPO solution and reported native demonstrations of 8λ and 16λ bidirectional DWDM. It also described detachable broadband fibers, serviceability, and known-good-die testability. | This is a supplier announcement describing a solution and demonstrated features. It does not by itself establish independent customer qualification, production yield, or comparative manufacturing maturity. |
These disclosures use different measures and describe different product contexts, so they cannot be ranked as if they were a common qualification test. Request the evidence that corresponds to your own volume, operating conditions, and deployment schedule.

Compare optical and electrical interfaces on a like-for-like basis
Build one comparison sheet and require every supplier to identify whether a figure is measured, simulated, or a target, along with its test conditions. Include:
Recommended Free Tools
- Wavelength band, modulation format, baud rate, bit rate per lane, and lane count.
- Reach, fiber type, optical power, link-loss budget, and receiver sensitivity.
- FEC assumptions, BER target, operating temperature, and any stated margin.
- Electrical host interface and the system boundary used for power or performance figures.
The public Intel and ST descriptions do not provide a complete, normalized end-to-end link-budget comparison. Intel lists DR and FR examples; ST describes 200 Gb/s-per-lane PAM4 operation for PIC100-based modules. Those figures are not directly interchangeable without matching lane count, FEC, reach, and operating conditions. For a design decision, use the relevant design kit, module specification, and qualification data for the intended application rather than comparing headline rates alone.
Choose a laser strategy that fits the package and service model
Determine whether the design uses integrated lasers, hybrid or heterogeneous integration, or external/pluggable laser sources. The choice affects where heat is generated, how light couples into the PIC, what can be screened before assembly, and whether a source can be replaced or made redundant without replacing a larger assembly.

Intel highlights integrated on-die laser arrays and wafer-scale testing. GF’s CPO announcement describes wavelength-multiplexing demonstrations and package testability features. These examples illustrate different implementation evidence; neither establishes a best laser architecture for every data center. Ask for the actual system-level evidence, including thermal conditions, source redundancy, coupling losses, screening coverage, and field-replacement procedure. (Intel; GlobalFoundries)
Make fiber coupling and package test first-order criteria
For NPO and especially CPO, the fiber-to-chip interface can determine whether a design is practical to assemble, test, and maintain at scale. A low-loss coupling result alone is not enough: alignment tolerance, broadband and polarization behavior, assembly yield, connectorization, and rework all matter.

Corning describes high-channel-count fiber-array units with precise alignment, designs that can mix 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. Evaluate connector access, fiber routing, rework, and service procedures alongside optical loss; a fiber assembly that works in a lab setup may not be convenient to handle inside a production system. Corning’s CPO overview describes these fiber and connector considerations.
GF says SCALE supports detachable broadband fibers and known-good-die testability. For any proposed platform, ask how detachability affects insertion loss and reliability, how package-level yield is measured, and which components can be isolated or replaced in the field. GF’s announcement identifies these as features of its solution, but a supplier-specific qualification is still needed for your intended system.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Assess ecosystem, capacity, and supply risk
Check access to the process design kit and design support, qualified packaging partners, test availability, capacity commitments, geographic diversification, and supply of lasers, detectors, fiber, and connectors. Ask who owns integration and failure analysis across the PIC, optical engine, package, and host system; a platform can meet its component specification and still be difficult to deploy if responsibilities or interfaces are unclear.

TrendForce identifies InP laser supply, manufacturing yield, serviceability, and connector standardization as CPO commercialization risks. It characterizes NPO as a near- to mid-term option that can preserve modularity and multi-vendor sourcing, while CPO is aimed at more tightly integrated, high-power-density applications. These are market-analysis observations, not a substitute for supplier-specific capacity commitments or system qualification. TrendForce’s 2026 analysis also forecasts the CPO/NPO market growing from around US$100 million in 2025 to more than US$39 billion by 2030; this is a forecast, not a measured market result.
Market projections can help explain why suppliers are investing, but they do not prove that a particular platform is ready for a particular production deployment. ST, citing LightCounting, projects silicon photonics’ share of optical technology in AI clusters rising from 43% in 2024 to 76% in 2030. That is a projection attributed by ST, not a measurement of current market share. ST’s page provides the attribution.
Use a common procurement scorecard
Score shortlisted options against the same application and evidence standard. Record unknowns explicitly rather than inferring them from a roadmap or marketing description.
| Evaluation area | Evidence to request |
|---|---|
| Application fit | Supported topology, reach, throughput, bandwidth density, latency, power, and thermal conditions for the target deployment. |
| Measured link performance | Like-for-like optical and electrical data, including lane configuration, loss budget, FEC, BER, temperature, and test setup. |
| Maturity and manufacturing | Current production status, qualification evidence, process controls, test coverage, known-good-die method, and capacity commitments. |
| Laser and fiber interface | Source architecture, coupling and fiber specifications, connector options, measured loss, and replacement or redundancy approach. |
| Package and field service | Package-level test results, rework and isolation procedures, fiber detachability implications, and service responsibilities. |
| Ecosystem and resilience | Design-kit access, packaging and test partners, supply plans for critical components, geographic resilience, and interface openness. |
| Total system economics | Comparable system power and cost for the intended configuration, including packaging, cooling, deployment, and maintenance assumptions. |
The public material reviewed here does not establish a shared independent yield benchmark, a like-for-like platform cost model, or complete cross-vendor link budgets. Those comparisons require supplier data tied to the actual design and operating conditions.
Make the selection conditional on deployment evidence
Favor the option whose architecture and evidence match the intended deployment, not the one with the most attractive headline specification. A modular pluggable approach may better fit a system that prioritizes serviceability and sourcing flexibility; an NPO or CPO approach may be appropriate when shorter electrical paths and higher density justify tighter integration. The decision should turn on verified link performance, package and fiber handling, qualification, support, and committed supply for that use case.
