Speaking of NDA's,
Please have a look at this document (39 pages I know it a long one but interesting) pertaining to the December 2015 MIT Inteconnect roadmap effort (silicon photonics)
http://photonicsmanufacturing.org/sites/default/files/twg_files/psmc_connector_roadmap_mod8_121515_.pdf
NDA's aren't just for POET as photonics "could" be really be the next big thing...
There is too many sections of this document that I could post as abstract. Therefore I suggest that you take an hour of your time this week-end to look at it.
Happy reading,
