Roadmapping the next generation of silicon photonics
Nature Communications 15, 751
A broad technology roadmap that treats integration, packaging, testing and system economics as connected constraints.
Selected reading
Evidence behind the assembly layer.
A concise reading room for the terminology, integration methods and system constraints behind this editorial resource.
Editorial standard
Selections favor peer-reviewed work that clarifies terminology, demonstrates an integration route or reveals a system-level constraint. Inclusion is not endorsement, and a research demonstration is not presented as a mature manufacturing standard.
