A nugget by Rainer found in a Lightmatter thread: In short, plug the Xscape laser onto a POET optical interposer, and that’s it.
------------
DL came to POET to contribute and learn resulting in own product being powered by POET.
ML came to POET to contribute and learn resulting in developing a special laser for own company.
Whoever embarks on the creation and selling of devices utilizing said laser, those devices will be powered by POET. There is nobody else.
