报告简介：
Abstract:The integration of micro actuators and other forms of movable structures within a silicon optical chip enables manipulating and motion control of micro-optical components, leading to a wide variety of photonic MEMS. In parallel, an important key for further development of microfluidic devices –in the lab-on-chip format– is the co-integration of optical technologies, including light sources and micro-optical components, within the microfluidic environments leveraging the broad range of light-matter interaction mechanisms and the high sensitivity of the optical resonators. In this talk, I will be presenting the challenges to realize high performance photonic MEMS and the recent advancements to overcome these challenges and mate with microfluidics. Demonstrations on miniaturized FTIR spectrometer, swept laser source and micro-optical scanners for optical coherence tomography, and resonance-based micro-refractometer, are discussed. The overall target is to transform the bulky instruments to the sensor scale devices with a decent performance.
微型换能器和硅基光学芯片内可移动结构的集成使得能够对微光学组件进行操纵和运动控制，从而产生各种各样的光子MEMS。与此同时，微流体设备的进一步发展的重要关键-片上实验室格式-利用了广泛的光和物质相互作用机制和光学谐振器的高灵敏度，是微流体环境中光学技术（包括光源和微光学元件）的协整。在本次演讲中，我将介绍实现高性能光子MEMS的挑战以及克服这些挑战并与微流体配合的最新进展。其中讨论了小型化FTIR光谱仪，扫描激光光源和用于光学相干断层扫描的微光学扫描仪以及基于共振的微折射仪的演示。总体目标是将笨重的仪器转换为具有良好性能的传感器秤设备。
