RE:RE:the poster I missA ton of money has been spent by the industry to keep silicon on track for the next big thing. And it appears more and more like the next big thing is optical. The silicon industry is doing whatever they can to get there. That industry has spent a fortune integrating silicon with wide band gap materials that can lase. The best they can do so far is homogenous integration. Which means bonding a III-V material to silicon as an implant (a tiny chip). Place it in a channel that can bond to the silicon without too much lattice mismatch. Very different thermal expansion co-efficient. And there is the rub. Silicon densities have gotten so extreme that they have to control the heat very precisely. The lase function unless it is state of the art and not some implant is not going to be that efficient. Now we are going to put it on a silicon chip that has high density? It is in my opinion why they are debating whether it even makes sense to try and do a lase function on a silicon chip. You need highly efficient lase but in order to make something that can a bond to silicon sacrifices are made. Will it ever be good enough to be extremely efficient? I doubt it but I don’t know enough about it to say for sure. But I think the POET management team does.
So they call this homogenious integration not monolithic integration because after all the money has been spent that really does not appear possible.
What blows my mind is that the reason they are trying to do this is exactly the reasons that makes POET unique. Single mode-reach capability. No one is talking about infinite extinction ratio except for POET.
Does not exist but POET says it does. Does get it… a Digital Opto-electronic Switch.
