As you know I am very optimistic regarding the completion of the technical milestones and also the commercialization effort. Keep that in mind as I respond to your questions...

action_or_reaction you pose an interesting alternative to the idea that the timeline has shifted due to the SSC's commercialization efforts. In your scenario, the technical team has shifted the timeline because the optical components have posed problems which are difficult or insurmountable.

First, fairchij is right that the delays in the completion of the milestones owe to the damage to the lab and also the lack of funding prior to the 2 PPs. So rather than look at the quarterly projections in 2012, versus those set in 2013, we should look at the changes in the order which were called for by the SSC.

So I'll answer the first question, as the others are about delays and not complications:

"1) Point 4 was ''validation of optical component at Mil Spec Fab Q4 2012''.

On the 2013 presentation point 4 was deleted and changed to ''p and n channel Complementary Heterostructure Field Effect...'' (so basically not optical part but eletrical component).

Why the validation of the optical component is not already completed, if it was supposed to be done at BAE?"

First, the optical validation remains, and wasn't deleted, only renamed and delayed. The new terminology is "Optical Thyristor - based Infrared Detector Array Fabrication and Validation"

I can't explain why the microwave and radio frequency capabilities took precedence over the optical integration. But, it's interesting to note that the work on this new MS took place at BAE while UConn was being repaired. They could easily have worked on the optical component instead of the CHFET. If further complicates the question of who decided the CHFET was more important. I don't think this was for BAE's IR sensor/emitter, because it would have been on the MS timeline all along.

I think Yan Zhang may have been working on a recent academic work that requried the RF capability (for PHd thesis?) .

Perhaps it was part of the NASA SBIR work.

Obviously, it could be for those reasons of for simpler reasons - just the fact that we want to show that POET can do what GaAs chips are already relied upon to do. Personally, I think that there is some guidance taking place here, maybe some of Lee S's early heads-up meetings with device makers and chip manufacturers (unofficial and without white papers) suggested they would be interested in licensing with RF capabilities. Or perhaps BAE will want POET for products other than a death ray IR detector/emitter. After all, they agreed to add that to their list of things to do at Nashua. What's their end?

I don't think we have to worry about problems in the development of the optical components. I think the SSC wants metrics on all the PET components for their meetings with device/chip makers. If there was a problem, I would think they would have rearranged (renumbered) the timelines again so that the optical components would have followed the HFET and Bipolar transistors. In a related point, I think that giving themselves only a month to complete 2 more optical MS (MS7 for sure and I think MS5 also), is not giving them enough time to work out any glitches. They had the opportunity to adjust the timeline when they added the 100nm MS and they didn't. This makes me think they are still on track for the end of September.
