NASA embraces Integrated Photonics Laser on a Chip,

Here is an extract from the article at:

Although integrated photonics promises to revolutionize space-based science and interplanetary communications, its impact on terrestrial uses also is equally profound, Krainak added. One such use is with data centers. These costly, very large facilities house servers that are connected by fiber-optic cable to store, manage, and distribute data. Integrated photonics promises to dramatically reduce the need for and size of these behemoths — particularly since the optical hardware needed to operate these facilities will be printed onto a chip. In addition to driving down costs, the technology promises faster computing power. “Google, Facebook, they’re all starting to look at this technology,” Krainak said. “As integrated photonics progresses to be more cost effective than fiber optics, it will be used,” Krainak said. “Everything is headed this way.”

Although I have not been able to determine a direct link to POET it all sounds rather familiar don't you think?.

Now that is announced with a cover photograph of Dr Krainak holdng a chip, one wonders whether more granularity might include some admissions on this front.
