Consumer bandwidth demand in Western countries is such that it is now being rationed by a number of ISPs through throttling and traffic management. Arguably, a bandwidth famine is needed to establish demand before research on maximising fibre bandwidth can resume. As an indicator for future progress, it is timely to review the astonishing strides in optical technology that have been made over the last 40 years. By far the most perfect transmission medium ever seen, the optical fibre together with its partner, the EDFA, currently satisfies world needs for both transmission loss and bandwidth. Furthermore, it has considerable capacity yet to be exploited and is making inroads into other markets. In the quiet years of telecoms, many have exploited the wealth of devices and techniques developed for telecommunications in other applications. Examples are in high-power laser processing, sensing in oil wells, and in the biosciences. The remarkable control of light achieved in photonics brings unprecedented opportunities for signal processing, molecular manipulation and even in industrial welding and cutting applications. Remarkably, in fibre amplifiers the milliwatts of telecommunications can be scaled to powers as high as Kilowatts. With beam combination, MW of continuous optical power could be within our grasp. The talk will review optical fibre developments across a number of areas in the context of historic developments. Particular emphasis will be given to recent developments, such as microstructured fibres, highly non-linear glasses and large-core, damage resistant fibres. It will focus on prospects for building novel technologies and applications through harnessing the properties of new optical fibres. 此报告为前沿讲座，欢迎全校师生踊跃参加。校学术委员会 2007年10月8日
