Silicon photonic ICs for prototyping

Imec offers an integrated silicon photonics platform targeted to the telecom, datacom and medical diagnostics industries: our Silicon Photonics Platform (iSiPP). The iSiPP platform co-integrates a wide variety of passive and active components, enabling competitive photonic integrated circuits for short reach optical interconnects.

Three flavors of iSiPP

Imec's iSiPP platform is SOI-based and comes in three distinct flavors:

  • iSiPP200: 200mm (8”) full platform (see table below)
  • iSiPP50G: 200mm (8”) simplified platform/flow (see table below)
  • iSiPP300: 300mm (12”) full platform
