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: options with TSV (through silicon via), microbumps and embedded microbumps are available in a 300mm (12”) platform
