Abstract title: Bound State in the Continuum LasersNontechnical description: The goal of this CAREER project is to investigate and develop for the first time a novel type of laser that exploits novel confinement method for light inspired by early theoretical works in quantum mechanics. The method can "plug leaky light cavities". Instead of limiting cavity losses the usual way by reducing the size and number of passages through which light can escape, the cavity's design produces destructive interferences that, when light is allowed to escape, the multiple waves that do so through different passages end up canceling each other. Discovering new principles that enable novel optical properties is crucial for the progress of photonics, the science of light. Applications of these systems include novel light sources for communication, sensing and imaging. This fundamental and experimental work will study the creation of those sources using engineered and nanostructured materials. The novel sources satisfy many requirements of photonics devices including small footprint, low power consumption and enhanced light-matter interaction. The project is integrated with rigorous educational and outreach activities, including training specialists in nanophotonics, classroom and laboratory training for students, outreach activities (annual winter workshop) towards underrepresented communities from high-school to graduate levels with emphasis on veterans and African-Americans.Technical description: Photonics sources and lasers have fundamental applications in science and technology. The discovery and implementation of new physical principle allowing unprecedented optical properties is paramount to the progress of photonic systems. The proposed research will investigate the physics of Bound State in the Continuum (BIC), initially believed to be a mathematical curiosity in quantum mechanics. BIC devices, especially sources, can be designed and implemented by engineering the decay channels of light in photonics systems using symmetry considerations. BIC offer a new paradigm in building unprecedented photonic cavities, sources and systems with unique optical responses. Applications of these systems include novel light sources with intriguing polarization singularities, surface lasers, sensing, and chip scale communications. BIC lasers satisfy many requirements for optical sources including scalability and low-threshold. The project objectives will be accomplished by combining expertise in design, fabrication, and characterization of unconventional cavities. The research will investigate BIC lasers and their new physics. The multidisciplinary project bridges the fields of laser physics, nanophotonics, nanofabrication and characterization. BIC lasers open new avenues in the study of light-matter interaction as they are intrinsically connected to topological charges and represent natural vector beam sources which are highly sought after in the fields of optical trapping, biological sensing, and quantum information.

摘要标题：连续介质激光器中的束缚态非技术描述：这个职业项目的目标是首次研究和开发一种新型的激光器，这种激光器采用了量子力学早期理论工作中对光的新的限制方法。这种方法可以“堵住漏光腔”。这种腔体的设计并没有像通常那样，通过减小光逃逸通道的大小和数量来限制腔体损耗，而是产生了破坏性的干扰，当光被允许逃逸时，穿过不同通道的多个波最终会相互抵消。发现能够实现新的光学特性的新原理对于光科学光子学的进步至关重要。这些系统的应用包括用于通信、传感和成像的新型光源。这项基础性和实验性的工作将研究如何使用工程材料和纳米结构材料创建这些源。这种新型光源满足了光电子器件的许多要求，包括占地面积小、低功耗和增强光与物质的相互作用。该项目与严格的教育和外联活动相结合，包括培训纳米光子学方面的专家，对学生进行课堂和实验室培训，向从高中到研究生的代表性不足的社区开展外联活动(年度冬季讲习班)，重点是退伍军人和非裔美国人。新的物理原理的发现和实现使其具有前所未有的光学性质，这对光子系统的进步至关重要。这项拟议的研究将调查连续统束束态(BIC)的物理学，最初被认为是量子力学中的数学奇观。BIC器件，特别是光源，可以通过利用对称性考虑来设计和实现光子学系统中的光的衰减通道。BIC为建立具有独特光学响应的前所未有的光子腔、源和系统提供了一种新的范例。这些系统的应用包括具有耐人寻味的偏振奇点的新型光源、表面激光、传感和芯片级通信。BIC激光器满足了对光源的许多要求，包括可扩展性和低阈值。项目目标将通过结合非传统型腔的设计、制造和表征方面的专业知识来实现。这项研究将研究BIC激光器及其新物理。这一多学科项目在激光物理、纳米光子学、纳米制造和表征领域架起了桥梁。BIC激光器在研究光-物质相互作用方面开辟了新的途径，因为它们本质上与拓扑电荷相连，代表着在光学捕获、生物传感和量子信息领域备受追捧的天然矢量光束源。
