Researchers at Tsinghua University have developed the OFE² optical AI chip, an innovation that uses light instead of electrical signals to process data—reaching speeds of 12.5 GHz while significantly reducing energy consumption.
The chip, known as the Optical Feature Extraction Engine (OFE²), represents a major step toward solving one of today’s biggest challenges: the massive power demands of AI data centers.
Optical computing is increasingly being explored as the next frontier, and this development reinforces that momentum.
