Ultrahigh-speed optical signal characterizaion for real-time evaluation and monitoring of photonics and electro-optic devices and systems

这个为期两年的战略项目涉及开发一套全面的简单实用的工具，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允许来自渥太华大学和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具有成本效益的，高性能的实时光信号监测解决方案，这对未来部署无处不在的，完全可重构的光纤和光纤无线“智能”网络至关重要。提出的光信号表征工具集将从两种不同类别的光脉冲处理方法构建，即1）基于光纤色散的实时光学傅立叶变换;和2）超快光学微分。该项目中开发的技术有两个重要的特点：1）它们的实现将基于简单、低成本的全光纤线性光学滤波器，与光纤完全兼容，并实现真正的异步在线网络操作; 2）它们将允许实现单次光信号/设备特性化，这是实际网络环境中实时光学监测的一个基本特征。我们的设计方法的灵活性和成熟的光子技术中，我们的概念可以被实现可能会导致成本/性能和大规模可重复的特性，这是成功的商业化的先决条件。最后，该项目所产生的新知识以及对与该工作不同阶段相关的高素质人员的培训肯定将有助于提高加拿大的全球竞争力，特别是在高技术部门。

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.
