Microlasers and microcavities based on three-dimensional photonic crystal

目的：研制紧凑型超高Q三维光子晶体谐振器，展示完全光子带隙的光泵浦和电泵浦低阈值微激光器。很明显，在边界之外有一个巨大的空间可以探索。在3D光子晶体中，最重要的是它们可以有一个完整的光子带隙。这一独特的功能使三维光能够在极小的空间内定位为共振态。在这个项目中，开发的UHQ微谐振器和低损耗波导的设计将以一种简单的制造方法建立，而不需要晶片键合，以演示通过光学和电子泵浦的3D光子晶体微激光器。所开发的技术将打破现有光定位技术设定的边界，为创造新的光定位器件和增强光学器件的性能和功能开辟了可能性。这些努力将影响其他科学界加强光本地化和光与物质相互作用的能力。开发的光局部化组件将成为研究凝聚态物理和光学物理的极佳试验台，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.
