Photonics and Optical Communication Research at the Hong Kong Polytechnic University

The Photonics Research Centre of the Hong Kong Polytechnic University is a multidisciplinary research centre with members from the Electrical, Electronic and Information Engineering, Industrial and Systems Engineering and Mechanical Engineering Departments. The main objective of the group is to form the basis of collaborations among the members of the Group. The broad background of the members in the centre has led to synergism in a broad range of topics including fibre communication systems, fibre sensors, GaN-based detectors and light emitters and application of laser technology in GaNbased optoelectronic and electronic devices. In some cases we have already found useful applications of our work relevant to the need of Hong Kong. In the sections below we will introduce the three major areas of research in the field of photonics at The Hong Kong Polytechnic University.
