To tackle the growing energy demands of AI, researchers at the University of Florida have built something dazzling. Their new chip, called a photonic joint transform correlator (pJTC), swaps electricity for light to handle one of AI's most power-hungry jobs. "In the near future, chip-based optics will become a key part of every AI chip we use daily," Sorger suggested. "And optical AI computing is next." It means this tiny, energy-smart chip could supercharge AI across the board, from nimble edge devices and high-performance computing rigs to sprawling cloud services.
