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.

光子学是光的技术，就像电子产品是电子技术一样。光纤光子学是指使用光纤指导，路线和转化光的技术。光纤因在电信中使用而闻名。他们值得诺贝尔物理学奖给查尔斯·考（Charles Kao），以“关于光纤维传输的开创性成就进行光学通信”。光纤还用于构建高功率激光器，分布式传感器，可以适合外科针头，照明系统等的生物医学问题。光电路（称为夫妻）也用光纤作为起始材料而构建。耦合器是通过融合两个或多个纤维的并排融合来制造的，然后将其拉到熔融纤维上，直到它们变得足够小，以使光可以从一种纤维转移到另一种纤维。 拟议的研究计划旨在进一步应用光纤摄影。正在开发在中红外地区运营的第一批耦合器，并在污染物，牙科，食品和药物安全等方面采用了应用。高功率夫妇被制造出来，在监测消融过程的同时，可以同时进行激光标记或手术。在量子级别运行的组件，生成了纠缠的照片，其著名的“远距离动作”，并且正在构建一个逐一检测照片的系统。还开发出比头发薄的微观纤维支架，以精确地对齐高密度光子电路。 这项研究的果实与加拿大光子学行业高度相关，在电信下降之后，这是主要应用程序。我们的研究扩大了他们的工具箱，即可以使用的可用组件来构建各种应用程序的系统。长期目标是让所有这些技术“离开实验室”并广泛使用，以过去在全球范围内商业化纤维组件的成功为基础。
