Optoelectronics, Electronics, Power, Nanotechnology and Biosystems Laboratory
Welcome to Optoelectronics, Electronics, Power, Nanotechnology and Biosystems Laboratory at Department of Electronic Engineering, City University of Hong Kong
Optoelectronics combines optical, physical, electronic, materials, and chemical sciences to produce faster, more efficient and cheaper ways of processing, transmitting and storing information. Optical techniques have revolutional information technology and replaed electric current and copper wire in telephone networks and telecommunication systems. Optoelectronics also has widespread applications in display (TV, laptop computrs, calculators), aircraft, medicine, retailing, manufacturing, entertainment and defence. Optoelectronics is vital to the future of any industrial nation, especially as its economic potential is only just beginning to be tapped
The Optoelectronics, Electronics, Power, Nanotechnology and Biosystems Laboratory at the City University of Hong Kong carries out basic and applied research in several aspects of optoelectronics which is a broad and expanding subject. Advances in optical and electronic devices depend very strongly on a better understanding of the optical, physical and chemical properties of materials, so that materials research and processing is essential. The laboratories has two Clean Rooms for this purpose, one devoted to planar, integrated optical devices, including both passive and active waveguides, laser and optical amplifiers. The other is for the study of interfaces, efficient light emission and fabrication of the new organic light-emitting diodes which are soon to have a major economic impact in the displays industry in Hong Kong and elsewhere. The two clean rooms provide a very clean, uncontaminated space for the processing of pure materials and devices. They contain a wide variety of analytical and fabrication equipment. Another major facility is a selection of high-power lasers for a number of projects, including the creation of diffraction gratings in optical fibres and planar waveguides. Fibre gratings are important new tools for improving the flexibility of optical signal processing. Other projects, are developing advanced techniques for new crystal lasers, optical harmonic generation, optical testing of components and structures, optical sensors, fault surveillance in optical systems and wavelength division multiplexing.
