Nonlinear Photonic Crystal Nanocavities and Waveguides

摘要ECCS-0757975H。吉布斯，亚利桑那大学智力优势：芯片上的固态纠缠是描述单个量子点和光子晶体平板纳米腔之间强耦合的一种方式。与被困在腔中的原子不同，量子点被固定在单片纳米腔内的位置。因此，交互是与时间无关的，使得操作更容易和可预测。平板技术适合于芯片上的波导互连和芯片之间的光纤互连，这表明它在纳米光子学和量子信息科学中具有巨大的应用潜力。具体目标包括将单个量子点确定地放置在腔场的反节点中，以及将纳米腔有效地耦合到光子晶体波导。这些纳米器件是非线性标准具的技术极限：单个光子可以控制另一个光子。在一个光子和一个量子点的水平上的非线性光学是令人兴奋的，应该得到充分的探索和发展。更广泛的影响：这项研究可能会对光电子和纳米结构行业产生额外的影响：它们雇用了我们的大部分学生。根据这项拨款，包括一名非裔美国人在内的两名研究生将接受纳米技术和纳米科学技术的培训，并接受量子光学、量子纠缠和量子信息科学基础知识的教育。该项目将进一步巩固与Axel Scherer在加州理工大学著名的光子晶体制造团队的富有成效的合作。这项研究将对在现实世界中实现量子信息处理所需的知识库做出重大贡献，并提高纠缠源的性能。

AbstractECCS-0757975H. Gibbs, University of ArizonaIntellectual Merit: Solid-state entanglement on a chip is one way to describe strong coupling between a single quantum dot and a photonic crystal slab nanocavity. Unlike an atom trapped in a cavity, the quantum dot is fixed in its position within the monolithic nanocavity. Therefore, the interaction is time independent, making manipulations easier and predictable. The planar slab technology lends itself to waveguide interconnections on the chip and fiber interconnections between chips, suggesting great potential for applications in nanophotonics and quantum information science. Specific goals include deterministic placement of a single quantum dot in the antinode of the cavity field and efficient coupling of a nanocavity to a photonic crystal waveguide. These nanodevices are the technological limit of the nonlinear etalon: a single photon can control another photon. Nonlinear optics at the level of one photon and one quantum dot is exciting and should be explored and developed fully. Broader Impacts: This research will likely have an additional impact on the photonics and nanostructure industries: they hire most of our students. Under this grant two graduate students, including one African-American, will be trained in the techniques of nanotechnology and nanoscience and educated in the fundamentals of quantum optics, quantum entanglement, and quantum information science. This project will further solidify the productive collaboration with Axel Scherer's renowned photonic crystal fabrication group at Caltech. This research will contribute significantly to the knowledge base required to implement quantum information processing in the real world and improve the performance of entangled sources.
