If my math is right, that is less than a second to transmit a blu ray disc. Not bad. When can we have a real NBN?
Three photons can switch an optical beam at 500 GHz
American photonics researchers have demonstrated an all-optical switching rig that can work at 500 GHz, controlling a beam using just three photons. High-speed switching in the optical domain is important for several reasons: it will let optical networks outperform anything that can be accomplished if the photonic signal has …
