Hi mystique,
in deed it seems a lot of the used structures of the POET transceiver were already tested at UCONN. But please note that here it is all about mass production in a pure play fab. My ideas to this issue:

1. Wavetek has much better hardware then the lab at UCONN and a lot of experienced engeneers. As POET is not that much different from their standard processing tech, I am sure they can do this job. No such issues with the sputter tool...

2. In a lab you can optimize the process and can fidle around a lot of parameters and solve occuring problems. Mass production is about speed of processing and yield.

3. Connecting single structures to a workable transceiver is a proof point. No idea what was done at UCONN in this respect.

4. Once the transceiver is working, they will have to optimize its performance. This will take time.

So - these milestones are no done deals, but I am very optimistic POET and Wavetek can do the job. There can be unforseen problems, but solving problems is the every day job of the envolved teams. So I hope we soon will receive news about the progress of this work.
