Ultrafast optical chip for ChatGPT

Artificial intelligence systems like ChatGPT are known for their high energy consumption. To address this, a team from the Center for Optics, Photonics, and Lasers (COPL) has developed an innovative optical chip capable of transmitting vast amounts of data at ultrafast speeds while delivering unprecedented energy efficiency. The core of this breakthrough, published in Nature Photonics, lies in harnessing the power of light for information transfer. Unlike traditional systems, the new chip utilizes not only the intensity of light but also the phase shift of optical radiation, adding a new dimension to the signal. This has enabled an increase in data transfer speed from 56 gigabits per second to 1 terabit per second—nearly 18 times faster. This new development promises a revolution for modern AI data centers, which currently occupy vast areas and consume significant energy.
