Intel unveils photonics roadmap
Intel laid out its silicon photonics technology blueprint at the OCP 2026 conference, positioning the technology as the core architecture for next-generation high-performance computing and AI data centres.
Nic Dubé, Intel's VP of data centre systems and solutions, described silicon photonics as a "golden hammer" and claimed Intel is the only foundry in the industry capable of volume production on 300mm InP wafers.
Intel said its integrated laser design uses a highly reliable light source requiring no additional maintenance, while also supporting industry standards for external light sources; preserving design flexibility across different system architectures and providing the industry with a US foundry supply source for multi-wavelength light sources.
Intel uses near-packaged optics (NPO) and co-packaged optics (CPO) to push optical components as close as possible to compute chips and network switch chips, shortening the transmission path for high-speed electrical signals and easing the signal attenuation and power burden of copper wiring in high-speed, long-distance scenarios.
Intel's stated energy target is to reduce the transmission energy of optical interconnect systems to under 5 picojoules per transmitted bit (5pJ/bit).
For data centre operators, if optical interconnects can push energy per transmitted bit below 5pJ/bit, it would directly affect the power allocation and thermal design of large-scale AI clusters, which in turn would influence rack density and total cost of ownership. However, before industry standards are settled and repair models are validated, most operators are expected to first verify reliability through small-scale deployments before gradually scaling up adoption.
