The global energy demand is projected to increase by almost 50% from 2012 to 2040. It is critical to address this challenge with new energy efficient technologies. The PI's research exploits high quality, low-dimensional materials to develop next generation devices. The proposed research continues the PI's endeavor in improving the efficiency of using energy through innovating photonic devices with group-III nitride nanostructures, far beyond the current state of the art. This program represents an ideal blend of dissemination of scientific knowledge across multiple disciplines and training of a new generation of high caliber scientists, and is unlike any other in Canada. It offers to train at least 4 students (2 PhD and 2 MEng) over the 5 year period. The long-term goal is to realize compact (size of a few cm3) and high power (watt-level) nanolasers in the visible and deep ultraviolet optical bands. To reach this long-term goal, it is imperative to understand the basic limitations of having such high power lasers, e.g., what are the key factors and what would be the optimized conditions. Therefore, in the short term, the PI's team aim to establish a fundamental understanding of these basic limitations, through developing color tunable and deep ultraviolet photonic crystal lasers with group-III nitride nanostructures, built upon the PI's preliminary results and intensive experience with these materials. Achieving these two short-term goals, the PI's team will establish strategies and building blocks to enable future high power compact nanolasers. Why is this research important? It is simply because we all need light and lasers are the most energy efficient technology to produce light; and the focused optical bands are highly relevant to our daily lives. In the visible, they will enable light sources that can be used for laser lighting, Li-Fi, among others; and with Li-Fi alone the projected market size is over $70B US dollars by 2023. In the deep ultraviolet, they will enable disruptive technologies, e.g., portable disinfection and bio/chemical sensing devices. This program will impact Canadians profoundly. Canada has vast north territories, where there are remote communities and deployed workers working there. In these areas, energy efficiency and device portability are critically important, as traditional energy sources, e.g., power grids, are hard to implement. The high power compact nanolaser technologies expected to be created through this program will positively impact their life quality, from lighting to drinking water disinfection, bio/chemical hazards detection, and so on. This program could also influence international communities. Recently, a student who wants to join the PI's research mentioned in email that the research is very attractive, because the potential technologies can help people in the student's home country. Clearly, the impact of this program on human society will surpass its impact on science and technology.

从2012年到2040年，全球能源需求预计将增长近50％。通过新的节能技术应对这一挑战至关重要。 PI的研究利用了高质量的低维材料来开发下一代设备。拟议的研究继续努力通过用氮化纳米结构创新使用能量来提高能源的效率，这远远超出了目前的最新状态。该计划代表了传播多个学科的科学知识和对新一代高素质科学家的培训的理想融合，并且与加拿大其他任何人都不同。它提议在5年期间至少培训至少4名学生（2位博士学位和2个Meng）。 长期的目标是实现可见且深紫外光带中的紧凑型（几个CM3的大小）和高功率（瓦特级）纳米震子。为了实现这一长期目标，必须了解具有如此高功率激光器的基本局限性，例如，什么是关键因素，以及优化条件是什么。因此，在短期内，PI的团队旨在通过开发具有颜色可调和深的紫外光子晶体晶体激光器，并建立在PI的初步结果和这些材料的强烈经验的基础上，从而建立对这些基本限制的基本理解。实现这两个短期目标，PI的团队将建立策略和组成部分，以实现未来的高力量紧凑型纳米棒。 这项研究为什么很重要？这仅仅是因为我们所有人都需要光线，激光是产生光的最节能技术。专注的光带与我们的日常生活高度相关。在可见的情况下，它们将启用可用于激光照明的光源，Li-Fi等。到2023年，预计的市场规模就超过了70亿美元。在深层紫外线中，它们将启用破坏性技术，例如便携式消毒和生物/化学传感设备。 该计划将对加拿大人产生深远的影响。加拿大拥有广阔的北领地，那里有偏远的社区和部署的工人在那里工作。在这些领域，能源效率和设备可移植性至关重要，因为传统能源（例如电网）很难实施。预计将通过该程序创建的高功率紧凑型纳米剂技术将对它们的生活质量产生积极影响，从照明到饮用水消毒，生物/化学危害检测等等。该计划也可能影响国际社区。最近，一位想加入PI在电子邮件中提到的PI研究的学生非常有吸引力，因为潜在技术可以帮助学生祖国的人们。显然，该计划对人类社会的影响将超过其对科学技术的影响。
