New Programmable Chip Slows Down Light for Better Computing

Topic: Technology

Researchers from Seoul National University and the University of Seoul have developed a new programmable photonic chip that can slow down light as needed. This breakthrough could help solve the computing bottleneck caused by the rapid growth of generative AI and large-scale AI models.

A team of researchers from Seoul National University and the University of Seoul has created a programmable photonic integrated circuit that can control how fast light moves. The team was led by Professors Namkyoo Park and Sunkyu Yu, working with Professor Xianji Piao.

The rapid growth of generative AI and large-scale AI models has increased the amount of computing power required by data centers and servers. Conventional electronic semiconductors are struggling to keep pace because they consume a lot of energy and face limits in how quickly they can transmit data. Optical systems could potentially move data at extremely high speeds while using less power.

However, light also presents a challenge. Because it naturally moves at a fixed speed, it's difficult to delay optical signals or temporarily hold them in place. This is essential for creating buffers and memory functions in optical computers.

To address this problem, the researchers designed a programmable photonic circuit that can control both the speed and shape of optical signals. Their approach provides more flexibility over 'slow light' than previously proposed methods.
