A research team has unveiled a microwave photonic chip that significantly enhances analog electronic signal processing, offering 1,000 times the speed and greater energy efficiency than existing processors. This innovation promises to revolutionize various sectors, including wireless communications and artificial intelligence.

A research team led by Professor Wang Cheng from the Department of Electrical Engineering (EE) at City University of Hong Kong (CityUHK) has developed a world-leading microwave photonic chip that is capable of performing ultrafast analog electronic signal processing and computation using optics.

The chip, which is 1,000 times faster and consumes less energy than a traditional electronic processor, has a wide range of applications, covering 5/6G wireless communication systems, high-resolution radar systems, artificial intelligence, computer vision, and image/video processing.

The team’s research findings were published in the prestigious scientific journal Nature titled “Integrated Lithium Niobate Microwave Photonic Processing Engine.” It is a collaborative research with The Chinese University of Hong Kong (CUHK).
