Do you think the heat generated and power requirements will decrease when photonic chips are available?
AFAIK, photonic circuits produce less heat than electric circuits. However I am aware that even when photonics becomes the norm [i.e. if is does], electricity will still be necessary for power supply.
I am thinking of a purely optical computer that is powered by a main
400 nm laser. The main laser if of course powered by electricity.
This optical PC contains 400 nm lasers but no LEDs. AFAIK, lasers tend to be more efficient that LEDs.
So do you think a chip based on lasers - instead of electricity - can be as real-time, hardware, and digital as possible while using the least amount of buffering required [hopefully none] and experiencing the least amount of latency possible [again, hopefully none] and at the same time being high-speed not getting hot enough to need any cooling equipment?
I think it would be easier to do this in photonics that electronics. Since electronics seem to easily overheat.
