After 50 years of effort, researchers made silicon emit light
Gaaah, please stop advertising optical computers as the technology that will overcome Moore's law. It makes no effing sense.<p>Wavelength of the light emitted by these devices: ~4000nm<p>Latest generation commodity CPU transistor structure size: 7nm<p>Add to that that photons really don't like being trapped; you essentially need a delay line and optical amplifier to hold them indefinitely (that's essentially the core technology my whole PhD thesis centers around), it makes them a really impractical thing to store bits with. Things with a rest mass can be stored easily, though. Things like, say, electrons!
