Even the EML business today it's all wirebonds on a very nice ceramic COS that's why they're expensive. So this integration play I mean your question earlier was why do we want to be silicon integrated because we are going to be integrating EML functionality. You just give it a supply current and you have a backside monitor that's all you get. Integration gives you monitoring, gives you health of your links, health of your optics. You can do exactly this: build a large interposer that talks optically between various ASICs. That's why you want to be a semiconductor based technology because you can derive value.  Piece parts, optical benches, micro lenses, isolators, focusers that kind of stuff it's Mom and Pop Shop you're never going to trigger volume and deliver value because you're going to be too expensive.
