18:29 – There are three critical devices that form the basis of our initial prototypes: the n-HFET, VCSELs – that’s Vertical Cavity Surface Emitting Lasers – and detectors, fabricated on the same epitaxial growth. We have previously demonstrated and announced world-class n-HFETs, through our partnership with BAE. I would like to announce some significant milestones achieved this past quarter on the VCSELs and detectors.

24:46 – We are often asked about our relationship with BAE, especially since we have not talked about them in some time. BAE has been a great partner to POET over a number of years. We transferred the n-FET process flow to BAE last year and were able to demonstrate excellent p-HEMT devices and characteristics at BAE on six-inch wafers. However, BAE lacks capability for VCSEL manufacturing that the POET platform categorically needs. When we joined the company, we actually started an evaluation of alternative partners that would have these capabilities in a foundry manufacturing environment. We therefore announced our initial foundry partnership with a commercial VCSEL foundry as they had the three things we were looking for:
