Light-matter interaction phenomena occurring at one millionth of one billionth of a second (femtosecond), ultra small billionth of a metre (nanometre) devices, extraordinary and exotic light behavior inside and at the vicinity of nanometer-sized metal structures (nanoplasmonics), and light manipulation in metals through the quantum property of electron spin (spinplasmonics) continue to influence numerous fields in science and advance our technology. Fundamentallly, these interactions manifest themselves as interplays between light quanta of photons and electrons. However, these fields have been independently evolving and need to be integrated onto a single platform. This proposal takes advantage of such emerging opportunities and brings the benefits offered by these fields. Under this umbrella, we combine unique nanoscale properties of light-driven electrons and structures with their inherent ultrafast response to investigate: how intense light field interacts with matter and how its intensity is enhanced when light is squeezed in nanostructures. We will exploit this interaction to generate visible light from silicon nanoplasmonic structures at unprecedented efficiency and manipulate light in ultra small cavities for integration with nanoelectronic devices. We will also explore a new field (plasmoelectronics) wherein electrical current is induced by light oscillations on a metal-dielectric interface (i.e. plasmons). This phenomenon is a prelude for the light-controlled nanoelectronics platform. This proposal charts new frontiers in novel technologies. For nanoplasmonics to complement nanoelectronics, there needs to be light-based devices analogous to key electronic components. One such element is a random access memory (RAM) -a computer memory being used to store data. However, to date RAM is only activated using electrical signals which limit its speed and versatility. Encouraged by our recent discovery of a non-volatile light-controlled random access memory, we plan to study this intriguing phenomenon for data storage and develop new exotic materials for application where light is used to store data. Likewise, innovation in terahertz (THz) spinplasmonics-where high frequency light is selectively used to manipulate and control electron spin for information processing- is a new intriguing paradigm for light-matter interaction. We plan to achieve full understanding of the physics of light-driven electron spin transport and develop advanced magnetic materials for compact and high-power THz radiation generation. The outcomes of this research not only advance our knowledge by unveiling new interesting physics of various phenomena and materials, but it also plants the seeds for future innovative technologies. Along with charting the aforementioned frontiers, the research will provide the students with strong training in cutting-edge technologies and unique hand-on skills that are highly sought after in the Canadian high-tech industry.

光线相互作用现象发生在十亿分之一（飞秒）的十亿分（飞秒），超过十亿米（纳米）设备，内部和附近纳米尺寸金属结构（Nanoplasmonics）的非凡和外来光线行为，非凡和外来的光线行为，通过电子自旋的量子特性（SpinPlasmonics）在金属中的光操纵继续影响科学领域的众多领域并推进我们的技术。基本上，这些相互作用表现为光子和电子光量子之间的相互作用。 但是，这些领域已经独立发展，需要集成到一个平台上。该提案利用了这种新兴的机会，并带来了这些领域所提供的好处。 在此伞下，我们将光驱动电子和结构的独特纳米级特性与它们固有的超快响应相结合：当光场在纳米结构中挤压时，强烈的光场如何与物质相互作用，以及如何增强其强度。 我们将利用这种相互作用，以在前所未有的效率下从硅纳米质结构中产生可见光，并在超小腔中操纵光与纳米电子设备集成。我们还将探索一个新的磁场（浆质电机），其中电流是由金属射电界面上的光振荡诱导的（即等离子体）。 这种现象是光控制的纳米电子平台的前奏。 该提议在新技术中列出了新的边界。为了使纳米质子学补充纳米电子学，需要有类似于关键电子组件的轻基设备。一个这样的元素是随机访问存储器（RAM） - 用于存储数据的计算机存储器。 但是，迄今为止，仅使用限制其速度和多功能性的电信号激活RAM。在我们最近发现非易失性的光制随机访问记忆的鼓励下，我们计划研究这种有趣的数据存储现象，并开发了用于存储数据的新的exotic材料。同样，在Terahertz（THZ）Spinplasmonics中进行的创新 - 高频光被选择性地用于操纵和控制电子旋转以进行信息处理 - 是一种新的有趣的范式，用于光 - 摩擦相互作用。我们计划完全了解光驱动电子自旋传输的物理，并开发出高级磁性材料，以产生紧凑和高功率的THZ辐射。 这项研究的结果不仅通过揭示各种现象和材料的新有趣的物理学来推动我们的知识，而且还为未来的创新技术种植了种子。除了绘制上述边界外，该研究还将为学生提供在加拿大高科技行业高度追捧的尖端技术和独特的手工技能方面的强大培训。
