3D Additive/subtractive laser manufacturing of photonic circuit and sensor micro-systems

光学玻璃已经转变为高科技设备，如镜片，纤维和薄膜，深入到我们的日常生活中。智能触控手机通过高速光纤网络实现高带宽通信和高效访问信息或连接到所有事物（物联网，IoT），从而使我们的日常生活受益。光传感器提高了公共安全，改善了我们的环境，并确保安全有效地利用资源。目前的提议利用最先进的超快激光器，在聚焦在这种透明介质中时，获得新型的激光相互作用物理形式。内部非接触式加工有望在纳米技术和纳米科学的前沿为光学元件的三维（3-D）增材或减材制造开辟新的途径。这种科学的方法建立在激光脉冲物理和时间整形的先进工具上，以预测和对抗在玻璃内部传播时的非线性扭曲。目标是控制三维相互作用的形状和引导物理动力学有利地改变玻璃的性质。我们的研究团队结合专业知识，创造新的3D玻璃制造工艺，将新型光学设备集成到先进望远镜、可穿戴技术、纤维成像工具、即时诊断和柔性引导手术导管的灵活形式中。这些方向与五个加拿大合作伙伴ELCAN Optical Technologies， Thalmic Labs, FiberTech Optica， ChipCare和LightMatter Interaction有关，这些合作伙伴目前正在使用或正在围绕超快激光器转变其制造能力。拟议的研究旨在加速加拿大高科技制造业在全球的领导地位。如果这个项目成功，将会给加拿大带来实质性的好处：(1)在3D光学加工领域的学术领导地位；(2)知识产权生成；(3)新的制造工艺和产品概念；(4)培养具有独特技能和专业知识的研发人员，从大学到加拿大工业环境的翻译；(5)为制造、销售和研发人员创造长期就业机会。

Optical glass has been transforming into high-technology devices, as lenses, fibres and film, that reach deeply into our everyday life. Smart-touch phones benefit our daily lives by enabling high-bandwidth communications and efficient access to information or connection to all things (Internet of Thing, IoT) through high-speed optical fibre networks. Optical sensors increase public safety, improve our environment, and ensure secure and efficient usage of resources. The current proposal exploits state-of-the-art ultrafast lasers to harvest novel forms of laser interaction physics when focused inside such transparent media. The internal non-contact processing promises to unfold new approaches for three-dimensional (3-D) additive or subtractive manufacturing of optical components at the forefront of nanotechnology and nanoscience. The scientific approach builds on advanced tools for physical and temporal shaping of laser pulses to anticipate and counter nonlinear distortions when propagating inside of the glass. The objective is to control the 3D interaction shape and steer the physical dynamics to favourably transform the glass properties. Our research team combines expertise to create new 3D glass manufacturing processes on which novel optical devices can be integrated into flexible forms of advanced telescopes, wearable technologies, fibre imaging tools, point-of-care diagnostics and flexible guided surgical catheters. These directions are connected with five Canadian partners, ELCAN Optical Technologies, Thalmic Labs, FiberTech Optica, ChipCare, and LightMatter Interaction, that currently are using, or are in a position to transform their manufacturing capacity around ultrafast lasers. The proposed research aims to accelerate the leadership of Canadian high technology manufactures globally. There are substantial benefits to Canada if this project is successful: (1) academic leadership in 3D optical processing; (2) generation of intellectual property; (3) new manufacturing processes and product concepts; (4) training of R&D personnel with unique skills and knowhow for translation from a university to a Canadian industrial environment; and (5) long-term job creation for manufacturing, sales and R&D personnel.
