Hi Boab,
I notice that Bluglass refers to DoD but also refers to DoW in their latest presentation:
BLGDA (they just did a consolidation), have a special semiconductor manufacturing process (Remote Plasma Chemical Vapour Deposition - RPCVD) which improves laser performance. They talk a good powerpoint:

NB: I hold BLG, so anything I say should be treated with kid gloves.
