And someone mentioned Rockley the other day. I have commented in the past that Rockley's big azz waveguides would be a perfect fit (pun intended) for light source insertion using POETs dielectric OI waveguides. Note the comment on the bottom of the article  I just linked to in the previoous post.

Earlier this month Rockley announced a $42 million joint-venture agreement with China’s HengTong Optic-Electric that is set to start producing silicon photonics transceivers later this year. Unlike other proponents focused on shrinking silicon photonics technology, Rickman’s view is that “bigger is better” when it comes to the technology, and his OPTO plenary may prove somewhat iconoclastic.
