Microlasers and microcavities based on three-dimensional photonic crystal

目的：本项目的目标是研制紧凑型超高Q三维光子晶体谐振器，并实现光泵和电泵低阈值光子带隙微激光器。学术价值：光子晶体技术目前受到二维光子晶体平板的限制。很明显，在边界之外有一个巨大的空间可以探索。3D光子晶体最重要的一点是它们可以具有完整的光子带隙。这一独特的功能使三维光定位在一个非常小的空间作为共振状态。在该计划中，开发的UHQ微谐振器和低损耗波导设计将通过一种简单的制造方法构建，而无需晶片键合，以演示通过光和电泵浦的3D光子晶体微激光器。所开发的技术将打破当前光定位技术所设定的边界，并开辟创建新的光定位设备的可能性，并增强光学设备的性能和功能。这些努力将影响其他科学界，以提高光定位和光-物质相互作用的能力。开发的光定位组件将是研究凝聚态物理和光学物理的绝佳测试平台，包括光-物质相互作用，量子信息科学和3D光学。此外，电流注入UHQ微激光器和谐振器将使光定位技术实用化。该计划为代表性不足的群体的学生提供教育，培训和研究机会。

Objective:The objective of this program is to develop compact ultra-high-Q three-dimensional photonic crystal resonators and demonstrate optically-pumped and electrically-pumped low-threshold microlasers defined in a complete photonic band gap.Intellectual Merit:Photonic crystal technology is currently limited by the boundary set by 2D photonic crystal slab. It is apparent that there is a huge space beyond the boundary to explore. The most significant thing in 3D photonic crystals is that they can have a complete photonic band gap. This unique feature enables three-dimensional light localization in an extremely small space as a resonance state. In this program, the developed UHQ microresonator and low-loss waveguides designs will be built by a simple fabrication method without wafer bonding in order to demonstrate 3D photonic crystal microlasers by optical and electrical pumping.Broader ImpactsThis program consists of research, training, and education components. The developed technology would break the boundary set by current light localization technology and open up possibilities of creating new light localization devices and enhance the performance and functionality of optical devices. The efforts would impact other scientific communities to enhance capabilities of light localization and light-matter interaction. The developed components for light localization would be excellent test beds for investigating condensed matter physics and optical physics, including light-matter interaction, quantum information science, and 3D optics. Furthermore, current-injection UHQ microlasers and resonators will make light localization technology practical. The program provides students in underrepresented groups with educational, training and research opportunities.
