Programmable Chip Tames Speed of Light | Science News

Scientists have just unlocked a revolutionary chip that can dynamically control the speed of light — a game-changer for optical computing. Traditionally, light moves at a fixed speed, making it nearly impossible to create the precise delays and buffers needed for complex systems. But this new programmable chip, developed by researchers at Seoul National University and the University of Seoul, uses a technique called CRIT to manipulate light’s speed and even its shape on the fly. Unlike fixed optical devices, this chip can adapt in real time — adjusting delays, bandwidth, and signal characteristics without needing new hardware. Simulations show it works even with manufacturing flaws, and could merge multiple functions like buffering, synchronization, and frequency conversion into one chip. The implications? Faster, more energy-efficient AI systems, smaller data centers, and breakthroughs in autonomous vehicles and quantum tech — all thanks to mastering the once-uncontrollable speed of light.
