Collaborative Research: Slow and Stopped Light Photonics with Atomic Spectroscopy Chips

该计划的目标是创造第一套基于量子干涉的慢光和停光光子器件。量子干涉创造了一些有史以来观察到的最强的光-物质相互作用，包括电磁诱导透明(EIT)、慢光和停光。存在大量可能的应用，包括光学数据处理、增强型传感、(量子)光存储器和量子信息处理。然而，到目前为止，还没有一个可行的平台将大量子干涉效应与光子器件集成在一起。该项目的智力优势是探索使用最近开发的自成一体的原子光谱学平台来创造一类新的基于量子干涉的光子器件。为此，将开发一种用于高温和高光密度工作的第二代空芯波导光谱芯片，并用于演示芯片上的受阻光。将展示一套基于量子干涉、慢光和阻挡光的新型正则光子器件，用于芯片规模的传感和光信号处理。这类新的器件将对非固体(原子)介质用于光子的使用产生革命性的影响。这项工作的更广泛的影响是联合几个领域，包括微制造、集成光学、原子光谱学和器件物理。这一合作项目将为研究生和本科生提供获得独特的多学科技能的机会。与该计划相辅相成的是一系列外展努力，分别通过加州大学洛杉矶分校和杨百翰大学现有的和成功的项目，从代表性不足的群体中招收本科生。

The objective of this program is to create the first set of quantum interference based slow and stopped light photonic devices. Quantum interference creates some of the strongest light-matter interactions ever observed, including electromagnetically induced transparency (EIT), slow light, and stopped light. A large number of possible applications exist, including optical data processing, enhanced sensing, (quantum) optical memories, and quantum information processing. However, to date there is no viable platform that combines large quantum interference effects with photonic device integration.The intellectual merit of this project is to explore the use of a recently developed self-contained atomic spectroscopy platform for creating a new class of photonic devices based on quantum interference. To this end, a second generation hollow-core waveguide spectroscopy chip for high temperature and high optical density operation will be developed and used to demonstrate stopped light on a chip. A set of novel, canonical photonic devices for chip-scale sensing and optical signal processing based on quantum interference, slow and stopped light will be demonstrated. This new class of devices will have transformative impact on the use of non-solid (atomic) media for photonics.The broader impacts of this work are to unite several fields, including microfabrication, integrated optics, atomic spectroscopy, and device physics. This collaborative project will provide opportunities for graduate and undergraduate students to acquire a unique, multidisciplinary skill set. The program is complemented by a number of outreach efforts to recruit undergraduate students from underrepresented groups through established and successful programs at UCSC and BYU, respectively.
