This Small Business Innovation Research Phase I project will develop a compact, rugged, rapidly and widely tunable, low noise, narrowband laser for use in microwave photonic processing applications. The key innovation in this effort is the use of a shaped ferroelectric in conjunction with a diffraction grating to produce an electro-optically controlled wavelength tuning element. The monolithic electro-optic tuning element, when combined with a semiconductor or rare-earthed doped gain media will result in an ultra-compact narrowband laser source that will be capable of extremely fast, mode hope free tuning over 100 GHz with a programmable chirping profile. Use of fiber coupled semiconductor optical amplifiers will ensure output power of at least 100 mW in a diffraction limited beam, and act as an optimal seed source for further possible amplification by a fiber laser amplifier. The research objectives of the Phase I effort include designing, fabricating, and demonstrating the successful operation of a prototype EO tunable laser. This effort will lead to advanced tuning capabilities in the field of microwave photonics. With the increasing demand for high-speed communications, there has been growing interest in developing techniques that can transmit microwave and/or millimeter waves over optical fiber. Low-noise tunable lasers would prove especially useful in this field. The technology will also be useful for improved Ladar sensors that can perform acquisition, tracking, and discrimination on missile and airborne platforms. Other potential applications include antenna remoting, beam forming networks for array antennas, feed networks for wireless communications, photonic processing of microwave signals, cable television signal distribution, sensor systems, and instrumentation. During the Phase I, the team will continue its effort in creating a broader impact in research and education through its onsite research program for university undergraduates and high school teachers.

这个小型企业创新研究第一阶段项目将开发一种紧凑、坚固、快速和可广泛调谐、低噪声的窄带激光器，用于微波光子加工应用。这项工作的关键创新是将成形铁电元件与衍射光栅结合使用，以产生电光控制的波长调谐元件。单片电光调谐元件与半导体或稀土掺杂增益介质相结合，将产生一种超紧凑的窄带激光光源，它将能够以可编程的啁啾曲线在100 GHz以上进行极快、无模式的调谐。光纤耦合半导体光放大器的使用将确保衍射受限光束的输出功率至少为100 mW，并作为光纤激光放大器进一步可能放大的最佳种子源。第一阶段的研究目标包括设计、制造和演示电光可调谐激光器原型的成功运行。这一努力将导致微波光子学领域的高级调谐能力。随着对高速通信的需求不断增加，人们对开发能够在光纤上传输微波和/或毫米波的技术越来越感兴趣。低噪声可调谐激光器将被证明在这一领域特别有用。这项技术还将用于改进的激光雷达传感器，可以在导弹和机载平台上执行捕获、跟踪和识别。其他潜在的应用包括天线远程处理、用于阵列天线的波束形成网络、用于无线通信的馈电网络、微波信号的光子处理、有线电视信号分配、传感器系统和仪器。在第一阶段，该团队将继续努力，通过其针对大学本科生和高中教师的现场研究计划，在研究和教育领域创造更广泛的影响。
