A Chinese research team has developed a new method to produce 3D optical chips in seconds, a process that previously took hours. This breakthrough could speed up the manufacturing of photonic chips, which are seen as a key component for next-generation artificial intelligence (AI) hardware. Photonic chips use light instead of electricity to transmit data. They are expected to overcome the bandwidth and power limits of traditional electronic chips. However, making them has been slow and complex, holding back their use in mass production. The team's new technique drastically reduces the time needed to create these chips. While details of the method are not fully disclosed, the achievement marks a significant step toward making photonic chips more practical and affordable. AI systems require huge amounts of computing power, and photonic chips could help meet that demand. By making production faster, this innovation may bring advanced AI hardware closer to reality.
