SBIR Phase I: Grating Structure for Diode Laser Wavelength Stabilization

95604752现场这个小型企业创新研究第一阶段项目将开发一种低成本技术，为二极管激光器提供高度可重复性的波长稳定。波分复用(WDM)通信网络、过程控制、医疗仪器和数据存储等应用都需要稳频二极管激光器。目前，只有使用昂贵的分布式反馈和分布式布拉格反射二极管激光器才能满足这些需求。这一阶段将提供一种集成的光学反射光栅结构，可用于稳定和锁定廉价的法布里-珀罗二极管激光器的输出波长，显著降低单频稳定源的成本。同样的光栅制作工艺可以应用于稳定半导体激光器输出波长的整个范围。该项目将建造并测量集成的光栅反馈设备的性能，然后在第二阶段将其集成到原型激光设备中。该产品预计将是一种以预设光学频率运行的稳频半导体激光器，将在WDM通信网络、过程控制、医疗仪器和数据存储中进行商业应用。这项技术的成本足够低，可能还会刺激这些市场以外的应用。

95604752 Field This Small Business Innovation Research (SBIR) Phase I project will develop a low cost technique to provide highly reproducible wavelength stabilization of diode lasers. Frequency stabilized diode lasers are required for applications including wavelength-division-multiplexed (WDM) communications networks, process control, medical instrumentation, and data storage. At present these needs can only be met using expensive distributed feedback and distributed Bragg reflection diode lasers. This Phase I will provide an integrated optic reflection grating structure which can be used to stabilize and lock the output wavelength of inexpensive Fabry-Perot diode lasers, significantly reducing the cost of single frequency stabilized sources. The same grating fabrication process can be applied to stabilize the entire range of diode laser output wavelengths. The project will build and measure the performance of an integrated grating feedback device which may then be integrated into a prototype laser device in Phase II. The product is expected to be a frequency stabilized diode laser which operates at a pre-set optical frequency and which will be commercially applied in WDM communications networks, process control, medical instrumentation, and data storage. This technology has a sufficiently low cost that it may also stimulate applications beyond these markets.
