Transceivers of the future

To connect thousands of processors and memories in high performance computing systems to run massive AI workloads, it can be done by pooling logics and memories through efficient interconnects. Over time, links for electrical signalling, limited by the loss of copper traces, are getting shorter as the bandwidth grows. Complex modulation formats, that are in use to compensate for the request of bandwidth over said links, require extra electronics such as FECs, ADCs, DSPs, making heavier cost and energy consumption.

Graphene Integrated photonics (GIP) provides superior performances to enable electro-optical cores for the transceivers of the future. Thanks to its unique physical properties, graphene photonics can reduce electronics and then complexity in the optical interconnections. The bandwidth-distance trade off is softened and processors/memories can be disaggregated and assembled in pools.

Graphene photonics

Breakthrough performance thanks to graphene

Graphene is compatible with many photonic materials, such as Silicon and Silicon Nitride, and can be synthetised and integrated through scalable wafer-level processes.

Our platform provides breakthrough performance: high bandwidth density, low-cost, low power consumption, high traffic capacity, temperature resilience.

Our products

Electro Absorption Modulators, Photodetectors, and Phase Modulators

The platform includes Electro Absorption Modulators (EAMs), Photodetectors (PDs), and Phase Modulators.

Integrability and flexibility are two key aspects of the platform; main characteristics of our electro-optical cores are:

  • 100+Gb/s NRZ per optical channel (EAM and PD)
  • Single-chip multi-channel flexible configurations (e.g. 1Tb/s capacity)
  • Integrated and dedicated driving electronics
  • Uncooled operation (>100°C)

Applications

Ultra-fast short-reach optical links at lower cost

The GIP platform satisfies the industry needs of ultra-fast short-reach optical links at lower cost. Application spaces are:

  • Intra-datacentre transceivers (pluggables, on-board optics, and co-package optics architectures)
  • I/O interconnectivity for AI/ML processing systems
  • Mm-Wave intra-antenna digital signal distribution for 5G/6G
  • Tunable sub-THz elements for smart antenna arrays
