This Small Business Innovation Research (SBIR) Phase I Project is intended to develop a miniature, low cost tunable laser enabled by the volume holographic filter technology already developed and commercially available today. The project will focus in developing the tunable light source for the blue-violet and near infrared range in order to address the above-mentioned markets. It is intended that the activities of this project will result in the development of a novel architecture: a self-aligned external cavity tunable laser (ECTL) enabled by an ultra-narrow band multi-line filter. The passive self-aligning nature of the proposed tunable laser is the main driver for low cost manufacturing. A unique feature of the architecture of the ECTL is its axial symmetry. This enables the use of axially symmetric components such as TO-can laser packages, lenses and volume holographic filters which further reduces the cost of manufacturing. The ultra-narrow band spectral light management capability of the volume holographic filter enables an extremely compact ECTL: an initial proof of concept tunable laser generated single mode light with a physical length of 12 mm and a couple nanometer tuning range.If successful the outcome of this project will have many commercial applications. The tunable laser technology is a platform that can be applied from the blue-violet (375 nm) to the infrared (4000 nm) and use commercially available low cost semi-conductor lasers. The attractive price/performance ratio of the match-box size tunable laser, over such a large spectral range, will open market segments in different fields that have been sparsely addressed by the state-of-the-art tunable laser technology. In particular, the technology can play a role in decreasing the rate of carbon emission by monitoring and optimizing efficiencies in combustion processes such as engines and coal plants. The technology could contribute to increasing the deployment of environmental stations by providing the optical source at a fraction of today?s cost.

该小型企业创新研究（SBIR）第一阶段项目旨在开发一种微型，低成本的可调谐激光器，该激光器由已经开发并可商业化的体积全息滤波器技术实现。该项目将专注于开发蓝紫和近红外范围的可调谐光源，以满足上述市场的需求。它的目的是，该项目的活动将导致在一个新的架构的发展：一个自对准的外腔可调谐激光器（ECTL），使超窄带多线滤波器。所提出的可调谐激光器的被动自对准性质是低成本制造的主要驱动力。ECTL结构的一个独特之处在于其轴对称性。这使得能够使用轴对称部件，例如TO-罐激光器封装、透镜和体积全息滤波器，这进一步降低了制造成本。体全息滤光片的超窄带光谱光管理能力实现了极其紧凑的ECTL：可调谐激光器产生单模光的初步概念验证，物理长度为12 mm，调谐范围为几纳米。如果成功，该项目的成果将具有许多商业应用。可调谐激光器技术是一个平台，可以应用于从蓝紫（375 nm）到红外（4000 nm），并使用商业上可用的低成本半导体激光器。火柴盒大小的可调谐激光器在如此大的光谱范围内具有吸引人的性价比，这将打开不同领域的细分市场，而这些领域目前还没有被最先进的可调谐激光器技术所解决。特别是，该技术可以通过监测和优化发动机和燃煤电厂等燃烧过程的效率，在降低碳排放率方面发挥作用。该技术可以通过提供今天的一小部分光源来增加环境站的部署。s成本。
