China and Breakthrough in Optical Chip Manufacture

Just the usual morning reading off Iranian sites:

China cuts optical chip manufacturing time from hours to seconds

Chinese researchers have developed a new technique that reduces the manufacturing time of optical chips from hours to seconds. The team has introduced a parallel manufacturing method that can convert 2D patterns into complex 3D structures on an entire 4-inch wafer in a single process.

Traditional methods are based on focused ion beam (FIB) techniques that create optical structures one by one, which is a slow and costly bottleneck.

The new approach produces thousands of structures simultaneously, significantly improving manufacturing efficiency.

The technology achieves angular uniformity of more than 97%, while reducing fabrication time by more than two orders of magnitude.

The method uses a broad ion beam to simultaneously transform thousands of 2D nanostructures into 3D designs, combining the ion beam with a self-folding “origami” approach.

This enables wafer-scale manufacturing while maintaining nanometer precision.

The advancement could help bridge the gap between highly customized optical designs and large-scale manufacturing.

As AI models become larger and more complex, the demand for faster and more efficient computing hardware is increasing. Optical connections offer higher bandwidth and lower power consumption than traditional electrical connections.

Translating optical structures into 3D space enables denser chip designs, reduced signal interference, and new functionalities that are difficult to achieve with 2D architectures.

Chinese scientists have solved a major bottleneck in optical chip manufacturing. By turning hours of work into seconds, this advancement could accelerate the development of next-generation integrated 3D photonics for advanced computing, communications, and sensors.
