As much as I want to think they are going to send POET into space soon, there are a few things that make me think this is an MIT solo effort. First off, this is the same kind of thing OPEL is doing with NASA (see this NR). POET will be a better choice when their device is ready because of minimal SWaP and since it is in GaAs it is natually rad-hard.

Here's couple of pieces I found that suggest MIT has developed the lasercom to be used on this upcoming launch:

I think Taylor's work is associated with Glenn Research Center, not Goddard and in any case, we have to give Taylor time to finish his PII work. It's a 2 year grant, so I think he'll need another year to complete the prototype mentioned in the NR.

Having said all that I'd love to be proven wrong. OPEL did add a milestone to add RF capabilities to POET last quarter and that does relate to the device they are making for NASA. So you never know!
