Paint-on Laser Brings Optical Computing Closer

holy_calamity writes "New Scientist has a story about a laser made by painting a solution of semiconductor crystals onto glass. It could be used to break the interconnect barrier by having optical interconnects, the interconnect barrier threatens Moore's law unless a faster way of connecting chips is found."

Re:Interconnect barrier?

Well, I don't have any direct sources, but: The interconnect barrier means that while chip size keeps decreasing, the interconnects between sections of chips, and even between individual chips themselves aren't able to be made much smaller, so things like resistance, capacitance, and inductance get in the way with the bigger interconnects. Basically, the interconnects can't keep up with the growth of the chips themselves.
