This two-year Strategic Project is concerned with the development of a comprehensive set of simple andpractical tools for ultrahigh-speed optical signal characterization entirely adapted to a fiber-optics networkenvironment. The proposed theoretical and experimental research will allow the two university teams from theUniversity of Ottawa and the INRS-EMT, in collaboration with their non-academic partners, to lead Canadianand international efforts in searching for cost-effective, high-performance real-time optical signal monitoringsolutions of essential importance for the future deployment of ubiquitous, fully-reconfigurable optical andfiber-wireless "intelligent" networks. The proposed optical signal characterization toolset will be constructedfrom two different classes of optical pulse processing methods, namely 1) real-time optical Fouriertransformation based on optical fiber dispersion; and 2) ultrafast optical differentiation. Two importantdistinctive features of the techniques to be developed in this project are: 1) their implementation will be basedon simple, low-cost all-fiber linear optical filters, fully compatible with fiber optics and enabling trulyasynchronous in-line network operation; and 2) they will allow achieving single-shot optical signal/devicecharacterization, an essential feature for real-time optical monitoring in a practical network environment. Theflexibility of our design approach and the maturity of the photonics technologies in which our concepts can beimplemented may well lead to the cost/performance and mass-reproducible characteristics which areprerequisite to successful commercialization. Finally, the new knowledge generated from this project and thetraining of highly qualified personnel associated to the different stages of this work will certainly contribute toenhance Canada's global competitiveness, especially in high-technology sectors.

这个为期两年的战略项目致力于开发一套全面的简单而实用的工具，用于完全适应光纤网络环境的超高速光信号表征。拟议的理论和实验研究将使渥太华大学和INRS-EMT的两个大学团队与他们的非学术合作伙伴合作，领导加拿大和国际努力寻找经济高效、高性能的实时光信号监控解决方案，这对未来普遍存在的、完全可重构的光纤和光纤-无线“智能”网络的部署至关重要。所提出的光信号表征工具集将由两类不同的光脉冲处理方法构成，即1)基于光纤色散的实时光傅里叶变换和2)超快光微分。该项目将开发的技术的两个重要特点是：1)它们的实施将基于简单、低成本的全光纤线性滤光器，与光纤完全兼容，并能够实现三级异步在线网络操作；2)它们将允许实现单次激发光信号/设备特征，这是在实际网络环境中实时光监控的基本特征。我们设计方法的灵活性和我们的概念可以在其中实现的光子学技术的成熟度很可能导致性价比和可大规模重现的特征，这是成功商业化的先决条件。最后，这一项目产生的新知识以及与这项工作的不同阶段相关的高素质人员的培训必将有助于提高加拿大的全球竞争力，特别是在高技术部门。
