The growing popularity of parallel computing, and the arrival of multicore processors and 3D chips are leading to data traffic jams both on-chip and chip-to-chip. However, the report believes that these trends are also creating opportunities for chip-level optical interconnects.
Avago, Finisar, IBM and Samtec have all proposed optical engines for chip-level interconnect. These miniaturized optical assemblies are currently the most mature technology available for this application and will generate revenues of $235 million in 2019. However, with their attached connectors and heat sinks, optical engines may prove too large for complex optical interconnection environments, such as in the coming generation of Exascale supercomputers.
