A great articte!!!
Did you read this?
“In the long run, everything should be monolithic,” he adds. “You shouldn’t be gluing anything down or soldering anything together. But that doesn’t mean that the world will wait until you can do it monolithically. We definitely will go through a hybrid phase, where solder-bumping the photonic subsystem onto the electronic control chip will be the early packaging solution. It solves the problem of trying to integrate two disparate processes with nanometer transistors and micron optics.”
I guess exactly this is what POET is doing at the moment, knowing that they already have all the IP to do it monolytic.
