After re-reading Poet's news about LightBar-C, my impression of what it said was way off base.  This press release had nothing to do with cell phones or home computers.  It did mention Lidar, cloud computing, 5 G communications and artificial intelligence applications.  It also stated that this new LightBar-C product would extend the optical interposer into new applications and markets.  I have also learned that there are a large number of people on this site who do know what they are talking about.  I think that my best bet, on this site, is to simply listen and learn.
