Once again, it's time to stop reading into presentations, stop dreaming and REALLY look at what is being said. The slide talks about who is in on PIC optical solutions and lists POET optical interposer as part of that group. Denselight produces lasers that POET purchases for their optical interposer and optical engines. Rajan Rajgopal clearly states this in the presentation.

Poet is a customer of Denselight lasers. Denselight is NOT a customer of POET optical interposer technology.
