Welcome to Centre for Optoelectronics (COE)


The Centre for Optoelectronics (COE) conducts research in the materials growth of III-V compound semiconductors (III-arsenides, III-phosphides, III-nitrides) by Metal Organic Chemical Vapour Deposition (MOCVD) and Molecular Beam Epitaxy (MBE), characterisation of semiconductor materials (optical, electronic and microstructural studies), fabrication and characterisation of Optoelectronics devices (semiconductor lasers and LEDs, quantum well and quantum dot photodetectors and optical waveguides), as well as the development of microelectronic unit processes (metalisation, reactive ion etching, inductively coupled plasma etching, rapid thermal processing, oxidation) and the simulation of Optoelectronics fundamental processes.




  • Acquisition of new knowledge in optoelectronics technology and related fields through research and participation in international and local forums with the aim of serving as a resource centre for local industries.
  • Transfer of technology and dissemination of knowledge to society and industry by offering collaborative research projects, short courses and seminars.
  • Manpower resource development in the latest technologies through participation in research programmes.
