Optical Microresonators for Integrated Sensors and Devices

集成光学微谐振器是本研究计划的核心。这些器件分别由于其极高的质量（Q）因子和非常小的模态体积（V）而表现出非常高的时间和空间光限制水平。*该提案针对两种特定类型的光学微谐振器：片上平面法布里-珀罗腔（1）和硫属化物玻璃回音壁模式（WGM）微腔（2），并将它们带到更高水平的片上集成。因此，我们建议开发新的集成方法，并将其应用到这两种类型的微谐振器。片上共面Fabry-Perot腔将成为生物医学和环境应用光学鼻的基本元件，而硫系玻璃WGM谐振器将为光谱学和生物传感应用中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通过两种类型的光学微谐振器直接应用于环境和生物医学应用，但所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.**
