Green light is 200nm, but we are already approaching 2nm with electronics, wouldn't that make any equivalent light CPU 100x larger/slower?

- automatic6131 5y agoThis has two false assumptions, one being that the process number (a marketing number chiefly), has any physical meaing. And another that you can compare it to the wave length of light. And also green light is 500-560nm.
- poulpy123 5y agoLarger, yes, slower no since it uses light as a transmission and not electrons
- e2le 5y agoWouldn't it be possible to run multiple concurrent processes on the same CPU using many different wavelengths of light?
- mmmBacon 5y agoWhy would shorter wavelength light make computation faster? Silicon is a great absorber below about 1000nm so infrared wavelengths are used. 200nm is ultraviolet.
