On September 3, 2025, the internationally renowned physics media Physics World published a feature article titled “Broadband wireless gets even broader thanks to integrated transmitter,” highlighting our center’s latest research achievements in ultrabroadband wireless communication systems.

 The report provides a detailed introduction to the integrated transmitter developed by our team based on a thin-film lithium niobate photonic chip. This device can seamlessly process an exceptionally wide spectrum of signals—from below 1 GHz to above 100 GHz—using the same set of laser and resonator. This technological breakthrough overcomes the limitations of traditional multi-band systems, which require discrete components and suffer from severe noise accumulation. It offers a universal and reconfigurable integrated platform solution for next-generation technologies such as 6G, holographic communication, remote surgery, and the dense interconnection of the Internet of Things (IoT).

 In the article, Professor Alan Willner, a member of the U.S. National Academy of Engineering and a distinguished professor at the University of Southern California, remarked:

 “How can we flexibly and cost-effectively use different radio-frequency bands to transmit high-speed data? Should we rely on multiple separate systems for microwaves, millimeter waves, and terahertz waves? Using a single, tunable, and reconfigurable integrated platform to cover all these bands is undoubtedly a better approach. This research represents an important step in that direction.”

 This authoritative recognition further underscores the core value of our center’s work — providing a universal, reconfigurable integrated platform that paves the way for dense interconnectivity in future 6G wireless communication.
