This Small Business Innovation Research (SBIR) Phase II project will enable the fabrication of waveguides in potassium titanyl phosphate (KTP) containing Bragg gratings with specified spectral and electro-optic characteristics. These characteristics include reflectivity, bandwidth, central wavelength, and electro-optic tuning range. To achieve this goal, the relationship between the processing steps used to form the Bragg grating and its resulting spectral and electro-optic properties will be fully quantified. The ability to control the spectral characteristics and electro-optically tune these gratings will enable a broad range of new and commercially useful devices. Using the processing steps developed, an array of Bragg gratings will be fabricated with each grating optimized for stabilizing the wavelength of a laser diode. Translating the waveguide array with respect to the laser diode will tune its wavelength. This novel tuning technique will have significant technical and cost advantages over other tuning techniques.Potential commercial applications include tunable filters for active dispersion compensation, high-speed add/drop filters for wavelength division multiplexing (WDM), and a broadly tunable source for test and evaluation of network components. Other applications include stabilizing laser diodes for spectroscopy, seeding high power lasers, and frequency doubled diode-based replacement lasers for low power Argon-Ion and helium cadmium (HeCd) lasers.

这一小型企业创新研究(SBIR)第二阶段项目将能够在磷酸钛钾(KTP)中制造含有特定光谱和电光特性的布拉格光栅的光波导。这些特性包括反射率、带宽、中心波长和电光调谐范围。为了实现这一目标，将充分量化用于形成布拉格光栅的加工步骤与其所产生的光谱和电光特性之间的关系。控制光谱特性和对这些光栅进行电光调谐的能力将使一系列新的商业有用的设备成为可能。利用开发的工艺步骤，将制造布拉格光栅阵列，每个光栅都经过优化，以稳定激光二极管的波长。相对于激光二极管平移波导阵列将调谐其波长。与其他调谐技术相比，这种新的调谐技术将具有显著的技术和成本优势。潜在的商业应用包括用于有源色散补偿的可调谐滤波器、用于波分复用(WDM)的高速分插滤波器，以及用于测试和评估网络组件的广泛可调的源。其他应用包括稳定用于光谱的激光二极管，种子高功率激光器，以及用于低功率Ar离子和氦镉(HeCd)激光器的基于倍频二极管的替代激光器。
