项目摘要
The field of nonlinear optics has been intensely investigated since the advent of the laser in the 1960s. It entails the study of strong light interaction with matter, where exotic effects, such one colour of light converting to another colour, can be realized. Ever improving laser technology and fabrication methods have opened the door to nonlinear optics at very small length scales down to a billionth of a meter, called “the nanoscale”, for myriad applications. Underlying these technological developments is a need to understand the details of how light interacts nonlinearly with materials, and how to use that interaction to design processes and devices for further technological advances.
The overarching, long-term goal of Dr. Ramunno's research program is to use and develop state-of-the-art theoretical and computational techniques to investigate nonlinear optics at the nanoscale, in several research areas in photonics. Over five years, she will train graduate students, who will work with undergraduates and postdoctoral fellows toward the following scientific objectives. The first is to understand how images of cells and tissues are formed using a microscopy based on nonlinear optics, including what are the nanoscale limitations of such imaging, and how these may be overcome for applications such as understanding disease processes and early disease diagnosis. The second objective is to understand the mechanisms underlying laser machining of materials, and how this nonlinear interaction can be controlled to create new technologies, such as nanoscale 3D printing. The third is to design nanoscale devices to engineer the production of light, from the visible up to extreme ultraviolet radiation, for applications including communications, microscopy and laser machining. As the fabrication such nanoscale devices gets ever more precise, down to the one nanometer level, new paradigms of computational modelling are required, and Dr. Ramunno will develop these with her trainees.
Dr. Ramunno has a proven track record in each area, as well as established collaborations with experimental and industrial colleagues. These collaborations, including with world-class researchers at uOttawa, will contribute to the success and impact of the proposed research, and provide unique and varied research and career opportunities to students. This work is made possible by her cutting edge computational tools and access to high performance computers, including the most powerful supercomputer in Canada.
自20世纪60年代激光器问世以来,非线性光学领域一直受到人们的广泛关注。它需要研究强光与物质的相互作用,在那里可以实现奇异的效果,例如一种颜色的光转换为另一种颜色。不断改进的激光技术和制造方法为非线性光学打开了大门,其长度尺度可低至十亿分之一米,称为“纳米级”,可用于无数应用。这些技术发展的基础是需要了解光如何与材料非线性相互作用的细节,以及如何利用这种相互作用来设计工艺和设备,以实现进一步的技术进步。
Ramunno博士的研究计划的总体长期目标是使用和开发最先进的理论和计算技术,在光子学的几个研究领域中研究纳米级的非线性光学。在五年的时间里,她将培养研究生,他们将与本科生和博士后研究员一起努力实现以下科学目标。首先是了解如何使用基于非线性光学的显微镜形成细胞和组织的图像,包括这种成像的纳米级限制是什么,以及如何克服这些限制以用于理解疾病过程和早期疾病诊断等应用。第二个目标是了解激光加工材料的机制,以及如何控制这种非线性相互作用以创造新技术,如纳米级3D打印。第三个是设计纳米级设备,以工程师的光的生产,从可见光到极紫外线辐射,应用包括通信,显微镜和激光加工。随着这种纳米级器件的制造变得越来越精确,低至1纳米级,需要新的计算建模范例,Ramunno博士将与她的学员一起开发这些范例。
博士Ramunno在每个领域都拥有良好的业绩记录,并与实验和工业同事建立了合作关系。这些合作,包括与uOttawa的世界级研究人员的合作,将有助于拟议研究的成功和影响,并为学生提供独特而多样的研究和职业机会。这项工作是由她的尖端计算工具和访问高性能计算机,包括加拿大最强大的超级计算机。
