Photonics is the technology of light, much as electronics is the technology of electrons. Optical fibre photonics refers to technologies using optical fibres to guide, route and transform light. Optical fibres are widely known for their use in telecommunications. They merited a Nobel Prize of Physics to Charles Kao for “groundbreaking achievements concerning the transmission of light in fibers for optical communications”. Optical fibres are also used to build high-power lasers, distributed sensors, biomedical probes that can fit inside a surgical needle, illumination systems, etc. Optical circuits, called couplers, are also built with optical fibre as the starting material. Couplers are fabricated by fusing two or more fibres side-by-side, and then pulling on the fused fibres until they become small enough that light can transfer from one fibre to the others. The proposed research program aims to enable further applications of optical fibre photonics. The first couplers operating in the mid-infrared region are being developed, with applications in remote sensing of pollutants, dentistry, food- and medicine-safety, and others. High power couplers are fabricated, enabling simultaneous laser marking or surgery while monitoring the ablation process. Components operating at the quantum level, generating entangled pairs of photons with their famous “spooky action at a distance”, and systems detecting photons one by one are being built. Microscopic fibre holders, thinner than a hair, are also being developed for precise alignment of numerous fibres to high-density photonic circuits. The fruits of this research are highly relevant for the Canadian photonics industry, very diversified after the decline of telecommunications as the primary application. Our research enlarge their toolbox, that is, the available components with which they can build their systems for various applications. The long-term goal is to have all these technologies “get out of the lab” and become widely available, building on past success in commercializing fibre components world-wide.

光子学是光技术，就像电子学是电子技术一样，光纤光子学是指使用光纤来引导、路由和转换光的技术，光纤因其在电信领域的应用而广为人知。物理学奖授予高锟“在光通信光纤传输方面取得的突破性成就”光纤还用于构建高功率激光器、分布式传感器、可安装在内部的生物医学探针。手术针、照明系统等。光学电路（称为耦合器）也是以光纤为起始材料构建的。耦合器是通过并排熔合两根或多根光纤，然后拉动熔合的光纤直至它们变成一体而制成的。足够小，光可以从一根光纤传输到另一根光纤。 拟议的研究计划旨在实现光纤光子学的进一步应用，正在开发第一批在中红外区域工作的耦合器，其应用领域包括污染物遥感、牙科、食品和医药安全等。耦合器的制造可以同时进行激光打标或手术，同时监控在量子水平上运行的组件，通过其著名的“幽灵般的远距离作用”产生纠缠的光子对，以及逐一检测光子的系统。一种比头发还细的微型光纤支架正在开发中，用于将大量光纤精确对准高密度光子电路。 这项研究的成果与加拿大光子学行业高度相关，在电信作为主要应用的衰落之后，我们的研究扩大了他们的工具箱，即他们可以用来长期构建各种应用系统的可用组件。长期目标是在过去在全球光纤组件商业化方面取得的成功的基础上，让所有这些技术“走出实验室”并得到广泛应用。
