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.

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。该小型企业技术转让 (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光学光谱仪。 此类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其尺寸、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）元件来创建新型光谱仪。我们提出了这些元件之间独特的功能分离，以实现小型化，这是纯集成光学或纯微光学设计所无法实现的。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。这些设备更广泛的影响/商业潜力将是宽带光谱传感器，其数量级比目前可用的最小设备小。 这种衍射成像微型光谱仪有望促进涉及使用光学光谱的微系统的行业领域的变革。
