It is interesting that Suresh pointed out that the POET optical interposer can provide an integrated light source for silicon photonics and also that they are seeing high interest for  ASIC’s;

POET’s waveguide integrated active indium phosphide components that are developed as part of its Optical Interposer platform solutions provide a light source that can be integrated into silicon photonics devices, enabling cost advantages of wafer scale integration.

We're also seeing high interest for future applications of our Optical Interposer to enable direct optical interconnect into ASICs.

From GF website:

GF fabs in East Fishkill, New York and Singapore are actively developing SiPh solutions. The solutions leverage collaborative research and development innovations, high-volume manufacturing capabilities and advanced packaging, including passive alignment fiber attach that draws on extensive, in-house ASIC expertise.

GF’s SiPh portfolio includes:

·        An industry-first silicon photonics solution built on 90 nm technology and featuring:

o   Monolithic integration of RF and digital elements, silicon photonics and fiber coupling

o   Electro-optic PDK that enables co-design of both electrical and optical components at 1310 nm

o   Extensive investment in test capabilities, from wafer to module level, and including wafer characterization that enables fine tuning of SiPh manufacturing processes based on real-time measured results

o   Fast prototyping through cost-effective multi-project wafer (MPW) runs

·        Strong development roadmap for next-generation, higher data rate systems, including:

o   300 mm manufacturing and advanced lithography designed to deliver best-in-class performance and yield

o   Optimized components for polarization and wavelength diversity, low power and low loss

o   High bandwidth RF/analog interconnect for 50+ Gbaud systems
