Advancements in Photonic Computing
Photonic computers are emerging as a promising alternative to traditional electronic computing, especially for artificial intelligence applications. They utilize light to perform calculations, which enables much higher computing bandwidth, allowing for data transmission rates that significantly surpass those of electronic systems. One of the key advantages is their enhanced energy efficiency, with light traveling through optical fibers without generating the heat typically associated with electronic computation. Recent research has demonstrated that using a less coherent light source, like a super luminescence LED, can improve the performance and controllability of these photonic processors.
