Fairchij: So I can only assume that his point of reference is one of the amount of money that industry has typically spent in the quest to achieve monolithic integration. That would be the only way I could make any sense of that statement. Re inherent high cost of monolithic integration.

Well, I put that into an innocent little question to Mark, see http://fibereality.com/blog/singapore-globalfoundriescoherentpoet/#comment-7513:

Thanks, Mark, for your explanation! However, I am wondering what you mean by “inherent high cost of monolithic integration”. As I understand it, the idea of monolithically integrating the laser – or lasers (plural) – is to AVOID the costs incurred by having to use external lasers, not to mention reduced space and power consumption of the POET solution.
