OECC/ACOFT is a co-location of the 19th OptoElectronics and Communications Conference (OECC) and the 39th Australian Conference on Optical Fibre Technology (ACOFT). The OECC, established in 1996, is an annual conference which publishes proceedings and scientific research articles as a result of its conferences. OECC has conducted annual meetings since its establishment up to the present year. With an international scope, the areas of focus for the OECC are annual meetings in the Asia Pacific region, centered on the optoelectronics and optical communications profession. The function of the meetings are to report, discuss, exchange, and generate ideas which advance the disciplines of optoelectronics and optical communications. Communicating current and future applications related to these disciplines are also a function of these meetings. The CLEO Focus theme provides a forum for presentation and discussion of important new research directions with significant potential for future impact on the mainstream themes of OECC in telecommunications. Additionally there will be presentations on important adjacent areas of science and technology where developments have the potential to change the telecommunications landscape. This theme will provide attendees with the opportunity to get a good overview of the emerging topics that will influence the future technology roadmap.
