STTR Phase II: Diffractive Imaging Micro-Spectrometer

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该小企业技术转让（STTR）第二阶段项目旨在开发具有高分辨率和宽工作波长范围的小型化光谱仪。 这些设备的实现将开辟重要的新应用领域。 限制当前光谱仪使用的因素包括它们的尺寸、重量、复杂性和成本。 该项目旨在使用集成光学（即主要是2D）元件以及微光学（3D）组件来创建一种新型光谱仪。我们提出了一个独特的分离这些元素之间的功能，允许小型化，这是不可用于纯集成光学或纯微光学设计。微型光谱仪的2D部分在平面波导中实现。3D部件安装在波导板的顶部。这些设备的更广泛的影响/商业潜力将是一个宽带光谱传感器，比目前可用的最小设备小几个数量级。 这种衍射成像微型光谱仪预计将促进与使用光谱学的微型系统有关的工业部门的变革。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This Small Business Technology Transfer (STTR) Phase II project seeks to develop miniaturized optical spectrometers with high resolving power and wide operating wavelength ranges. The realization of such devices will open up important new applications areas. Factors which have limited the usage of current spectrometers include their size, weight, complexity, and cost. This project seeks to use both integrated optical (that is, mainly 2D) elements as well as micro-optical (3D) components to create a new type of spectrometer. We propose a unique separation of functions between these elements that allows for miniaturization, which is not available with pure integrated optical or pure micro-optical designs. The 2D part of the microspectrometer is implemented in a planar waveguide. The 3D part is mounted on top of the waveguide slab. The broader impact/commercial potential of these devices will be a broadband spectral sensor that is orders of magnitude smaller than the smallest devices currently available. This diffractive imaging micro-spectrometer is expected to promote transformative changes in industry sectors dealing with micro-systems that use optical spectroscopy.
