Photonics is a key enabling technology of the 21st century. NSERC DG funding will allow my team to exploit light-matter interaction for applications ranging from solving key manufacturing problems to exploring novel nanostructures. Our focus is on unravelling the dynamics of the process, and using light in innovative ways to control it. Powered by new collaborations and multi-million dollar investments in infrastructure, we will help solve two of the major technical challenges of our age, namely how to make our society more sustainable and more secure. We will also expand the frontiers of ultrasensitive sensing and ultrafast dynamics. To become more efficient with our resources, we need new manufacturing processes that generate lighter and more efficient components with less waste. Laser-based additive manufacturing (LAM) promises to revolutionise manufacturing with its ability to directly "write" intricate 3D metal components, but its widespread adoption is being impeded by the complexity of the intense light/matter interaction. By high-speed in situ monitoring during laser writing, we will solve the LAM quality assurance and control problem. Due to the great advances in fiber optic networks, information flows like never before but loss of security can have dire consequences. Almost all secure transmissions rely on public key encryption, but experts agree that its obsolescence is only a matter of time. It is crucial that we move quickly to encryption systems guaranteed by physical law, such as quantum key distribution (QKD) which relies on bits encoded onto single photons. A significant roadblock to widespread QKD implementation is the lack of appropriate quantum optical sources that can be scaled up to meet technological needs. We will develop high brightness, high fidelity single-photon sources integrated onto a chip, exploiting standard semiconductor fabrication technology. Mechanical systems provide exquisitely sensitive probes of the world around us, and when inserted into a optical cavity, can be controlled and read out by light. We will explore the ultimate quantum limit of hybrid mechanical-optical systems (e.g., single-atomic thick membranes, single-photon light fields) to discover new capabilities for quantum mechanical and optical state creation, transduction of quantum information, and creation of high-sensitivity sensors working at the ultimate quantum limit. Timing of this proposal is critical: DG-funded HQP will be able to exploit the recently CFI-funded Queen's Nanaophotonics Research Centre ($7.3M). Outcomes of this research include: training of 11 researchers (plus 15 undergraduates) in fields of key importance to Canadian industry, novel methods of using lasers for precision manufacturing, novel nanomaterials for secure telecommunications and sensing, and improved understanding of the underlying physics present at the tip of a laser beam.

Photonics是21世纪的关键促成技术。 NSERC DG资金将使我的团队能够利用轻度互动来用于从解决关键制造问题到探索新型纳米结构的应用。我们的重点是阐明该过程的动态，并以创新的方式使用光来控制它。在新的合作和数百万美元的基础设施投资中，我们将帮助解决我们这个时代的两个主要技术挑战，即如何使我们的社会更具可持续性和更安全。我们还将扩大超敏感和超快动态的边界。 为了提高我们的资源效率，我们需要新的制造过程，以减少浪费，从而产生更轻，更有效的组件。基于激光的添加剂制造（LAM）有望通过其直接“写”复杂的3D金属组件的能力彻底改变制造，但由于强烈的光/物质交互的复杂性，它的广泛采用受到了阻碍。通过在激光撰写过程中的高速原位监测，我们将解决LAM质量保证和控制问题。 由于光纤网络取得了巨大的进步，因此信息流像以前一样流动，但是损失的安全性会带来可怕的后果。几乎所有安全的传输都取决于公共密钥加密，但是专家们认为其过时只是时间问题。至关重要的是，我们迅速采用了通过物理定律保证的加密系统，例如量子密钥分布（QKD），这些分布（QKD）依赖于编码在单个光子上的位。广泛的QKD实施的一个重大障碍是缺乏适当的量子光源，可以扩展以满足技术需求。我们将开发高亮度，高保真单光子源集成到芯片上，利用标准半导体制造技术。 机械系统提供了我们周围世界的精确敏感探针，当插入光腔时，可以通过光控制和读取。我们将探索混合机械 - 光学系统（例如，单原子厚膜，单光子光场）的最终量子极限，以发现新的功能，用于量子机械和光学状态的创建，量子信息的转导以及高敏感性传感器的最终量子量限制。 该提案的时机至关重要：DG资助的HQP将能够利用最近由CFI资助的女王鼻虫研究中心（730万美元）。这项研究的结果包括：在对加拿大行业至关重要的领域中对11位研究人员（加15名本科生）的培训，使用激光进行精确制造的新方法，新颖的纳米材料，用于安全的电信和感知，并提高对存在于激光束的潜在物理学的理解。
