"A new roadmap, the Heterogeneous Integration Technology Roadmap for Semiconductors (HITRS), aims to integrate fast optical communication made possible with photonic devices with the digital crunching capabilities of CMOS.

Speaking at The ConFab, Bill Bottoms, chairman and CEO of 3MT Solutions, said there were four significant issues driving change in the electronics industry that in turn drove the need for the new HITRS roadmap: 1) The approaching end of Moore’s Law scaling of CMOS, 2) Migration of data, logic and applications to the Cloud, 3) The rise of the internet of things, and 4) Consumerization of data and data access.

He also said that all the components exist to make very complex photonic integrated circuits, including beam splitters, microbumps, photodetectors, optical modulators, optical buses, laser sources, active wavelength locking devices, ring modulators, waveguides, WDM (wavelength division multiplexers) filters and fiber couplers. “They all exist, they all can be built with processes that are available to us in the CMOS fab, but in no place have they been integrated into a single device. Getting that done in an effective way is one of the objectives of the HITRS roadmap,” Bottoms explained."
