Microwave photonic chips have taken a revolutionary step forward in the field of analog electronic signal processing and computation. Led by Professor Wang Cheng from the Department of Electrical Engineering at City University of Hong Kong, a research team has successfully developed a cutting-edge microwave photonic chip that outperforms traditional electronic processors in terms of speed and energy consumption. This breakthrough has opened doors to a wide array of applications in various sectors, including wireless communication systems, radar systems, artificial intelligence, computer vision, and image/video processing.
The chip developed by Professor Wang’s team is a thousand times faster than conventional electronic processors while consuming significantly less energy. This remarkable feat was achieved by combining ultrafast electro-optic conversion with low-loss, multifunctional signal processing on a single integrated chip. The team’s research efforts have resulted in a chip that can perform high-speed analog computation with ultrabroad processing bandwidths of 67 GHz and exceptional computation accuracies, making it a game-changer in the field of analog signal processing.
The key to the impressive performance of the chip lies in its integrated microwave photonic processing engine based on a thin-film lithium niobate (LN) platform. This innovative approach enables the chip to perform a multitude of processing and computation tasks for analog signals with unparalleled speed and precision. The research team’s collaborative efforts with The Chinese University of Hong Kong have culminated in the development of a chip that combines high signal fidelity, low latency, and compact size, setting a new standard in microwave photonics technology.
The significance of the research conducted by Professor Wang’s team extends beyond the development of a high-performance microwave photonic chip. By leveraging the unique properties of lithium niobate, often referred to as the “silicon of photonics,” the team has paved the way for a new research field – LN microwave photonics. This breakthrough has the potential to revolutionize electronic signal processing and computation by enabling the creation of compact, high-fidelity microwave photonics chips that offer low latency and superior performance.
The research led by Professor Wang Cheng and his team represents a monumental step forward in the field of analog signal processing and computation. The development of the world-leading microwave photonic chip opens up new possibilities in a wide range of applications, from wireless communication systems to artificial intelligence. By combining speed, energy efficiency, and functionality in a single integrated chip, the team has set a new standard for microwave photonics technology and laid the foundation for future advancements in electronic signal processing.
