CAREER: Theory and Application of Reflective Microring Resonators

目的：本项目的目标是对反射式微环反射器进行表征、建模和利用。PI提出了通过在微环谐振器中集成布拉格反射器来设计新的器件功能。微环放大了光栅反射，形成了具有高反射率、窄线宽和无旁瓣波纹的紧凑型反射镜。这些好处将减少信道串扰，并可能导致较低功率、较高数据速率的通信系统。智力价值：智力的价值在于，这项研究将促进对该设备的科学理解，并向光子界展示其作为基本元素的潜力。PI建议利用他在器件理论、激光、传感器和纳米制造方面的经验以及实验能力和资源方面的初步成果。这项研究具有潜在的变革性，因为它可能开启新的研究领域(新的设备和模型)，并实现不同的应用(干涉测量、计量学、射频光子学和通信)。将探索两个具体的应用：作为芯片上吸收光谱的腔体和作为可调谐激光器的反射镜。广泛的影响：更广泛的影响将是为下一代通信和消费电子创造新的设备。研究和教学将通过两门课程的开发而整合：实验研究原理？和光子器件的建模。来自代表性不足群体的学生的招募、保留和参与将通过指导、REU实习和为10-12年级女孩举办的新的电气工程夏令营来解决。将公布研究和教学的结果，以加强目前对反光微环装置和工程教育/推广方法的了解。

Objective: The objectives of this program are to characterize, model, and utilize reflective microring reflectors. The PI proposes engineering novel device functionality by integrating a Bragg reflector in a microring resonator. The microring amplifies grating reflection, creating a compact mirror with high reflectivity, narrow linewidth, and no side lobe ripple. These benefits would reduce channel crosstalk and potentially result in lower power, higher data rate communication systems. Intellectual Merit: The intellectual merit is that the research will advance scientific understanding of the device and demonstrate its potential as a fundamental element to the photonics community. The PI proposes to leverage his preliminary results in device theory, experience in lasers, sensors, and nanofabrication, and experimental capabilities and resources. The research is potentially transformative as it may unlock new lines of research (new devices and models) and enable diverse applications (interferometry, metrology, RF photonics, and communications). Two specific applications will be explored: as cavities for on-chip absorption spectroscopy and as mirrors for tunable lasers.Broader Impact: The broader impacts will be to create novel devices for next generation communications and consumer electronics. Research and teaching will be integrated through the development of two courses: Principles of Experimental Research? and Modeling of Photonic Devices. Recruitment, retention, and participation of students from underrepresented groups will be addressed through mentoring, REU internships, and a new electrical engineering summer camp for 10th-12th grade girls. Results from both research and teaching will be published to enhance the current understanding of reflective microring devices and engineering education/outreach methodologies.
