The research focus of the Circuits and Systems group is to introduce state-of-the-art innovations, which cover various technologies such as digital, analog and mixed-signal ICs, MMIC/RFIC, antennas, electromagnetic modelings and integrated multi-chip-modules into the design and implementation of modern electronic products/systems such as smartcard, RFID, software radio and WiMAX.

Our group is also actively engaged in industrial projects including the development of advanced RFID systems and components for consumer electronics products. In the last few years, the group has received over HK$ 25 Million from external funding agencies including industry and ITC (government-owned).

Our department is the first among all institutions in Hong Kong to introduce ASIC design into our undergraduate program and as a specialised field of research. Our major facility includes the most advanced RF Radiation Research Lab that is equipped with a 128-probe SATIMO near field spherical scanner, the most comprehensive communication tester and DASY5 dosimetric assessment systems which allows compliance testing of mobile phones with SAR limits. It is CTIA compliant and supports both TIS (Total Isotropic Sensitivity) and TRP (Total Radiated Power) measurements. It is ideal for testing mobile terminals, base station antennas as well as automotive antennas.

The VLSI and the microwave research laboratories are installed with a large number of workstations, PCs and a comprehensive and industrial standard suite of design software including Cadence, Mentor Graphics, Synopsys, ADS (advanced design system) and CST. State-of-the-art testing equipment such as logic analyzer, network/spectrum analyzer, multi-function signal generator, digital scopes, probe station, SAR tester and EMC chamber are also available.

The mission of the Solid State Electronics and Photonics Group is to conduct top-notch research and to develop innovative applications at various levels from electronic/photonic materials to devices and systems. The training of postgraduate students to conduct independent research in these areas will form an integral part of this mission.

Our group is actively engaged in several major research areas, namely, advanced electronic/photonic materials and devices; nanoelectronics and nanophotonics; optoelectronics and ultrafast optoelectronic systems; optical planar and fibre devices; silicon photonics; nonlinear fiber optics and optical communications; advanced electronic packaging technologies; flexible electronics; advanced technologies for renewable energy. The group has secured more than HK$ 100 million from RGC research funds in the past decade. Besides the group is also actively involved in applied research by securing more than HK$ 25 million in industrial projects.

Teaching staff members of the group are actively participating in numerous professional activities, and have served as symposium chairs or in program committees in international conferences, as well as members of editorial boards of technical journals. Currently there are one Member of US National Academy of Engineering; two Fellows of IEEE; one Fellow of OSA. Postgraduates of the group have received a number of prestigious awards, including the Graduate Student Fellowship Award by IEEE and Young Scientist Awards by Hong Kong Institute of Science.

The research and teaching activities of the group are supported by a number of ancillary laboratories with a few state-of-the-art facilities, which are designated for material processing, device fabrication, device/material characterization, optical instrumentation and measurements, fiber-optic communications, computer simulation.
