The aim of this proposed research is to address the modelling, design, demonstration and potential applications of ultra-wide-band (UWB) optical fibre amplifiers based on the Raman effect, induced by high power laser pumping of specially designed optical fibre, for future applications in optical fibre communication networks, ranging from inter-data-centre connections to metro/regional networks. Despite massive advances in the capabilities of optical fibre communication systems over the past two decades, enabled by digital coherent technology, internet traffic growth remains well above 20% per annum, and is forecast to continue on a strong trajectory for the foreseeable future. Delivering a seamless optical amplifier of unprecedented bandwidth is now seen by operators and their network equipment suppliers as the most practical and cost-effective way to increase the traffic carrying capacity of the billions of km of glass fibre that has been deployed worldwide, by making use of the wide low-loss window. The programme targets two specific designs of all-Raman amplifier: (i) a node-located, discrete-only parallel, dual-stage design, and (ii) a hybrid distributed-discrete dual-stage design, making use of the intra-node transmission fibre as a gain medium for part of the spectrum. These innovative designs are enabled by recent increases in laser pump powers and novel nonlinear Raman gain fibres, and a growing, general acceptance of Raman technology by all network operators, ranging from relatively conservative incumbents, such as Verizon, to more adventurous technology giants, such as google. New, nonlinear, modelling tools will be developed to overcome and support the significant experimental design challenges in manufacturing and operating our proposed UWB amplifiers, which with 300nm bandwidth offer approaching 10x the bandwidth of standard Erbium-doped fibre amplifiers used in today's networks. Key optical amplifier characteristics such as gain, noise figure, uniformity and nonlinearity will be measured stand-alone. UWB optical fibre communication system capacity improvements and performance will be evaluated in representative models of target networks, informed by our project partners, and compared with extensive in-line and recirculating loop UWB laboratory-based tests.

这项拟议研究的目的是解决超宽带（UWB）光纤放大器的建模，设计，演示和潜在的应用，基于拉曼效应，诱导高功率激光泵浦特别设计的光纤，为未来的应用在光纤通信网络，从数据中心间的连接，以城市/区域网络。尽管在过去二十年中，光纤通信系统的能力在数字相干技术的支持下取得了巨大进步，但互联网流量的年增长率仍远高于20%，预计在可预见的未来将继续保持强劲的增长势头。运营商及其网络设备供应商现在认为，通过利用宽的低损耗窗口，提供前所未有带宽的无缝光放大器是增加全球部署的数十亿公里玻璃纤维的流量承载能力的最实用和最具成本效益的方法。该计划针对两种具体的全拉曼放大器设计：（i）一个节点定位，离散只有并行，双级设计，和（ii）一个混合分布式离散双级设计，利用节点内传输光纤作为增益介质的一部分频谱。这些创新的设计是由于最近激光泵浦功率和新型非线性拉曼增益光纤的增加，以及所有网络运营商对拉曼技术日益普遍的接受，从相对保守的现任者，如Verizon，到更具冒险精神的技术巨头，如谷歌。将开发新的非线性建模工具，以克服和支持在制造和操作我们提出的UWB放大器方面的重大实验设计挑战，UWB放大器具有300 nm带宽，提供接近当今网络中使用的标准掺铒光纤放大器的10倍带宽。关键的光放大器特性，如增益，噪声系数，均匀性和非线性将被单独测量。UWB光纤通信系统的容量改进和性能将在目标网络的代表性模型中进行评估，由我们的项目合作伙伴告知，并与广泛的在线和循环回路UWB实验室测试进行比较。
