项目摘要

Increased connectivity is transforming our daily lives. Nowadays, virtual communities have a major impact on societal dynamics and sensor networks are helping in decision making processes. This massive flow of information is putting pressure on our communication infrastructure and drives the need for high bandwidth technologies. This Discovery grant (DG) will research photonic technologies to help us harvest and exchange data, meeting the future needs of intelligent communities. My objective is to increase the bandwidth of optical networks through innovations in optical fibers and integrated photonics, multiplying channels and capacity. The proposed research investigates an emerging paradigm for optical fiber transmission, called space division multiplexing (SDM), which consists of carrying multiple data streams in parallel on orthogonal fiber modes. Unfortunately, these modes exchange energy during propagation if the fiber is perturbed, mixing the information channels. The DG will examine how to achieve SDM transmission without inter-channel interference over the longest possible distance. I will design fibers that allow multiplexing over vector modes that are well separated, for example micro-structured polarization-maintaining few-mode fibers that increase the number of modes, while keeping effective index differences large and loss small. The fibers will be fabricated in-house at the Center for Optics, Photonics and Lasers (COPL) that is equipped with a full optical fiber fabrication facility, a unique infrastructure in Canada. All fiber properties, such as modal loss and cross-talk, will be thoroughly characterized. The goal of cross-talk free transmissions can only be achieved with mode multiplexers/demultiplexers of high quality. I will examine two technologies to generate and combine modes, firstly using optical fiber couplers and secondly using silicon photonic (SiPh). In the long term, SiPh offers the possibility to make a full transmitter that combines data carried on several wavelengths, polarizations and modes. I also propose to leverage this know-how in SDM technologies for sensing applications. I will investigate how multi-core fibers can make an optical fiber probe dedicated to shape sensing and displacement monitoring in permafrost. The close proximity between my laboratory, with state-of-the-art test equipment, and the COPL fiber fabrication team and infrastructure provides a great opportunity for high impact research in optical fiber technologies. Canada has a strong photonic industry, encompassing large telecommunication equipment manufacturers, as well as small and medium size photonic businesses that must constantly innovate to maintain their leadership position. In addition to its research outputs, this research program will provide a high quality training environment for young researchers who will be joining this dynamic industrial sector.
互联互通的增加正在改变我们的日常生活。如今,虚拟社区对社会动态产生了重大影响,传感器网络正在帮助决策过程。这种巨大的信息流给我们的通信基础设施带来了压力,并推动了对高带宽技术的需求。这项“探索补助金”将研究光子技术,以协助我们收集和交换数据,以满足未来智能社区的需求。我的目标是通过光纤和集成光子学的创新来增加光网络的带宽,增加信道和容量。提出的研究探讨了一种新兴的光纤传输模式,称为空分复用(SDM),它包括在正交光纤模式上并行传输多个数据流。不幸的是,如果光纤受到干扰,这些模式会在传输过程中交换能量,从而混合信息通道。总干事将研究如何在尽可能长的距离内实现无信道间干扰的SDM传输。我将设计允许在分离良好的矢量模式上复用的光纤,例如微结构的保偏少模光纤,它可以增加模式的数量,同时保持有效折射率差异大而损耗小。光纤将在光学、光子学和激光中心(COPL)内部制造,该中心配备了完整的光纤制造设备,这是加拿大独特的基础设施。所有的光纤特性,如模态损耗和串扰,将被彻底表征。无串扰传输的目标只能通过高质量的模式复用器/解复用器来实现。我将研究两种产生和组合模式的技术,首先使用光纤耦合器,其次使用硅光子(SiPh)。从长远来看,SiPh提供了制造一个完整的发射机的可能性,该发射机结合了在多个波长,偏振和模式下携带的数据。我还建议利用SDM技术在传感应用方面的专业知识。我将研究如何多芯光纤可以使光纤探头专用于形状传感和位移监测的永久冻土。我的实验室拥有最先进的测试设备,与COPL光纤制造团队和基础设施之间的距离很近,为光纤技术的高影响力研究提供了一个很好的机会。加拿大拥有强大的光子产业,包括大型电信设备制造商,以及必须不断创新以保持其领先地位的中小型光子企业。除了研究成果外,该研究项目还将为即将加入这个充满活力的工业部门的年轻研究人员提供高质量的培训环境。
