SBIR Phase I: Material Processing for Optimizing the Performance of an Embedded Bragg Grating

这个小企业创新研究第一阶段计划将确定主动控制嵌入非线性光波导器件的布拉格光栅光谱特性的可行性。 这项工作的关键创新之处是应用外场来控制嵌入式布拉格光栅。 初步计算表明，1 nm的调谐范围应该是可能的，速率高达10 GHz。 为了充分发挥电光控制布拉格光栅的潜力，将研究不同加工条件对光栅光谱特性的影响。 将具有一组特定光谱特性的电光可调谐布拉格光栅结合到标准非线性光学材料（例如离子改性磷酸钛氧钾）中的能力将极大地扩展材料的功能并实现广泛的新应用。电光可调谐布拉格光栅将打开广泛应用的大门，包括用于波分复用（WDM）、光谱学和远程通信的二极管激光器的直接高速频率调制。

This Small Business Innovation Research Phase I program will determine the feasibility of actively controlling the spectral properties of Bragg gratings embedded in nonlinear optical waveguide devices. The key innovation in this work is the application of an external field to control the embedded Bragg grating. Preliminary calculations indicate that tuning ranges of 1 nm should be possible with rates as high as 10GHz. To fully realize the potential of the electro-optically controlled Bragg grating, an investigation of the effect that different processing conditions have on the spectral properties of the grating will be made. The ability to incorporate an electro-optically tunable Bragg grating with a particular set of spectral characteristics into a standard nonlinear optical material such as ion-modified potassium titanyl phosphate will greatly expand the functionality of the material and enable a broad range of new applications.An electro-optically tunable Bragg grating will open the door to a broad range of applications, including direct high speed frequency modulation of diode lasers for wavelength division multiplexing (WDM), spectroscopy, and remote s
