The focus and discussion here has been on PET and the potential PDA. This is a high volume, high impact possibility. However, if POET realizes an uptake or adoption by the military (BAE), optical-electric company, or some PET PDA, any one of these possibilities would justify a higher share price.
Think of how small revenues would have to be from licensing to justify the current share price with a PE ratio of 10. And the prospect for seriously substantial growth is unbelievable.
I think that the current shareprice gives a fairly low probability of any of the potential markets adopting POET. When the first adoption happens, watch out.
