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阶段I项目将开发一个紧凑，坚固，快速且可调，低噪声，窄带激光器，用于微波炉光子处理应用。这项工作的关键创新是使用形状的铁电和衍射光栅的使用来产生电流控制的波长调谐元件。当与半导体或稀有掺杂的增益介质结合使用时，单层电磁调谐元件将产生超紧凑的窄带激光源，该激光源将能够通过可编程的chiring chir曲线进行快速，模式的无效调整超过100 GHz。使用纤维耦合的半导体光学放大器将确保在衍射有限梁中至少100 MW的输出功率，并充当最佳种子源，以进一步通过纤维激光器放大器扩增。第一阶段工作的研究目标包括设计，制造和证明原型EO可调激光的成功操作。这项工作将导致微波光子学领域的高级调整功能。随着对高速通信的需求不断增长，人们对开发可以通过光纤传输微波和/或毫米波的技术越来越兴趣。低噪声可调激光器将在该领域特别有用。该技术还将用于改进可以在导弹和空降平台上执行采集，跟踪和歧视的LADAR传感器。其他潜在的应用包括天线远程，阵列天线的光束形成网络，用于无线通信的馈电网络，微波信号的光子处理，有线电视信号分布，传感器系统和仪器。在第一阶段，团队将继续努力通过其在大学本科生和高中教师的现场研究计划对研究和教育产生更大的影响。
