This SBIR Phase I project will develop a 100 micron long lab-on-a-chip spectrometer to detect benzene, toluene, ethylbenzene, and xylenes (BTEX) and other compounds in contaminated ground water and methane and nitrous oxides in air emissions. The project will develop a photonic crystal slot waveguide device which will combine slow light effect in photonic crystal waveguides with large optical field intensity in a low index slot at the center of the photonic crystal waveguide. This will allow exact identification of analyte through spectroscopic signatures.The broader/commercial impact of the project will be realized with the successful demonstration of this technology that will permit this chip to be adapted to a wide range of contaminants in water and air media, and hence, could be very useful to activities in the environmental field.

SBIR一期项目将开发一个100微米长的芯片实验室光谱仪，用于检测受污染地下水中的苯、甲苯、乙苯和二甲苯（BTEX）和其他化合物，以及空气排放中的甲烷和氧化亚氮。本项目将开发一种光子晶体槽波导器件，将光子晶体波导中的慢光效应与光子晶体波导中心低折射率槽中的大光场强度相结合。这将允许通过光谱特征准确地识别分析物。随着这项技术的成功演示，该项目将实现更广泛的商业影响，这将使该芯片能够适应水和空气介质中的各种污染物，因此，对环境领域的活动非常有用。
