Paolo Costa, Partner Research Manager at Microsoft Research Cambridge, presents a breakthrough in AI infrastructure: using microLEDs to overcome scaling limitations in current communication technologies. Unlike copper (short range) and optics (high power), microLED links promise long reach, low power consumption, low cost, and high reliability—unlocking radical new AI cluster designs.
