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."
