Abstract Photonic materials are the backbones of optical communication, sensing and imaging systems. The advent of artificial intelligence, internet of things and human-machine interfaces require optical information perception, data communication and storage with a much higher bandwidth, smaller footprint yet extremely low power consumption. Bulk materials can no longer support these tasks. Development of advanced […]

Abstract The next frontier of the Internet of Things (IoT) lies in transforming today’s smart devices into collaborative cognitive agents – an ecosystem termed the Internet of Intelligent Things (IoIT). While current IoT systems center on raw data exchange, they fall short of enabling true collaboration: devices cannot share meaningful insights or align their objectives […]

Online via Zoom link: https://hku.zoom.us/j/2025021302 Abstract With the commercialization of 5G technology, research on 6G has emerged as a key focus in the field of wireless communications. In this talk, we explore three candidate waveforms for 6G, designed to meet its stringent requirements for throughput, reliability, and integrated sensing and communications (ISAC). We begin by […]

Abstract Recently, the International Telecommunication Union (ITU) has identified integrated sensing and communication (ISAC) as a primary usage scenario for the sixth-generation (6G) cellular networks in IMT-2030 Framework. As a result, future cellular networks will provide not only communication services, but also sensing services such as localization and tracking. However, how to exploit the existing […]

Abstract Federated learning is a distributed artificial intelligence framework, which allows multiple edge devices to train a single model collaboratively. In this talk, we first introduce a personalized federated learning algorithm which can tackle the issues of data heterogeneity and device heterogeneity. Then, we present a content-based viewport prediction framework for 360-degree video streaming, wherein […]

Abstract Traditional power electronic equipment has long relied on discrete active and passive components, with performance enhancements often requiring trade-offs. Despite technological advancements, manufacturing processes remain labor-intensive and largely unchanged for decades. The advent of wide-bandgap (WBG) power semiconductor devices, such as silicon carbide (SiC) and gallium nitride (GaN), has significantly reduced conduction and switching […]

Abstract There is simultaneously an interest for more energy-efficient hardware in challenging applications, as well as a drive to overhaul the von Neumann architecture toward more brain-like architectures. Compute-in-Memory (CIM) is one emerging paradigm addressing key memory bottlenecks such as bandwidth limitations, access latency, and high data movement energy in conventional computing platforms. In part […]

Abstract Engineering robust, solid-state quantum systems is amongst the most pressing challenges to realise scalable quantum photonic circuitry. While several 3D systems (such as diamond or gallium arsenide) have been thoroughly studied, solid state emitters in van der Waals (vdW) and two dimensional (2D) materials are still in their infancy. In this presentation, I will […]

Abstract Redox-based resistive switching random access memory (ReRAM) which is frequently discussed as a promising non-volatile memory as well as a central element in novel neuromorphic computing applications, is typically integrated in 1-transistor-1-resistor (1T1R) structures. While the access transistor is required as a selective device and acts as an effective current compliance during SET, it […]

Abstract Reactive power compensation plays a critical role in improving power quality, enhancing voltage stability, and optimizing the efficiency of electrical power systems. This presentation will first highlight the main applications of shunt reactive power compensators and provide an overview of key technologies, including Static Var Compensators (SVC), and Static Synchronous Compensators (StatComs). Then the […]
