We are just selling Denselight, I see nothing about a participation 2Biezz. 

"At the same time, a well-funded partner capable of making investments in both DenseLight and in additional manufacturing capacity will both support the anticipated ramp of POET's Optical Interposer and transform DenseLight into a world-class manufacturer with global market reach. In addition to being one of its potentially largest customers, we expect to remain engaged with DenseLight and its partner over the long term for the benefit of both companies."

So they hope to have a long-term relationship with a well-funded partner. Not bad!
