Optical Microresonators for Integrated Sensors and Devices

集成光学微谐振器是本研究项目的核心。这些器件分别具有极高的高质量(Q)因子和非常小的模态体积(V)，从而表现出非常高的时间和空间光约束水平。***本提案针对两种特定类型的光学微谐振器：片上平面内Fabry-Perot腔(1)和chalcogenide玻璃低语廊模式（WGM）微腔(2)，并将其提升到更高的片上集成度。因此，我们建议开发新的集成方法，并将其应用于两种类型的微谐振器。芯片上的平面内法布里-珀罗腔将成为用于生物医学和环境应用的光学鼻子的基本元素。硫系玻璃WGM谐振器将为光谱学和生物传感应用所需的中红外光的产生铺平道路。***虽然我们将开发的集成技术将直接通过两种类型的光学微谐振器应用于环境和生物医学应用，但开发技术的好处是旨在服务于更广泛的应用领域，涵盖电子，光子学和生物技术等领域的任何类型的集成传感器和系统

Integrated optical micro resonators are the core of this research program. These devices exhibit a very high level of temporal and spatial light confinement thanks to their extremely high-Quality (Q) factor and very small modal volumes (V) respectively.***This proposal targets two specific types of optical micro resonators: in-plane Fabry-Perot cavities on chip (1) and chalcogenide glass whispering gallery mode (WGM) microcavities (2) and to bring them to a higher level of integration on chip. Therefore, we propose to develop new integration approaches and to apply them to the two types of microresonators. The in-plane Fabry-Perot cavity on chip will be the basic element for an optical nose serving biomedical and environmental applications.The chalcogenide glass WGM resonator will pave the way for the generation of mid-IR light required in spectroscopy and biosensing applications. ***While the integration technology that we will develop will be directly applied through the two types of optical microresonators for environmental and biomedical applications, the benefit of the developed technology is intended to serve much wider application areas covering any type of integrated sensors and systems in fields as diverse as electronics, photonics and biotechnology.**
