摘要 | Configurations for in-situ gas detection are provided, and include miniaturized photonic devices, low-optical-loss, guided-wave structures and state-selective adsorption coatings. High quality factor semiconductor resonators have been demonstrated in different configurations, such as micro-disks, micro-rings, micro-toroids, and photonic crystals with the properties of very narrow NIR transmission bands and sensitivity up to 10−9 (change in complex refractive index). The devices are therefore highly sensitive to changes in optical properties to the device parameters and can be tunable to the absorption of the chemical species of interest. Appropriate coatings applied to the device enhance state-specific molecular detection. |
其他摘要 | 提供了用于原位气体检测的配置,包括小型化光子器件,低光损耗,导波结构和状态选择性吸附涂层。高质量因子半导体谐振器已经在不同配置中得到证明,例如微盘,微环,微环形和光子晶体,具有非常窄的NIR透射带和灵敏度高达10 -9 (复折射率的变化)。因此,这些器件对光学性质随器件参数的变化高度敏感,并且可以调节到感兴趣的化学物质的吸收。施加到装置上的适当涂层增强了状态特异性分子检测。 |
