Objective The objective is to investigate novel electro-optics and nonlinear optics approaches for generation of optical frequency combs and explore new applications of such novel light sources.Intellectual MeritCombining optical frequency combs, a technology that has revolutionized frequency metrology, with pulse shaping techniques provides new capability for precision synthesis of user-specified coherent ultrashort pulsed fields, termed optical arbitrary waveform generation (OAWG). However, OAWG technologies and applications are best suited to optical frequency combs operating at repetition rates significantly higher than those conveniently provided by current sources. Therefore, a new research program is proposed focusing first on novel photonics approaches for high repetition rate frequency comb generation and second on potentially transformative new applications thereby enabled. Generation approaches include novel combinationss of electro-optic phase modulation and nonlinear fiber optics with application to combs at tens of GHz rates; and nonlinear wave mixing in waveguide microresonators, with an emphasis on precise waveform generation at even higher repetition rates (hundreds of GHz). Investigation of high resolution, standoff optical imaging based on approaches inspired by synthetic aperture radar, enabled by comb-based techniques for measurement of broadband optical phase over optical fibers, is also proposed. Broader Impact This project should provide rich opportunities for broad student training in areas of cutting-edge technology within the atmosphere of a leading research group. Two Ph.D. students are included in the proposal budget. Graduate student training will be enriched through the opportunity to collaborate with researchers at the National Institute of Standards and Technology. Undergraduate students will also participate in this research. During the course of this project, Prof. Weiner also intends to leverage his recent textbook publication by placing his graduate level course on Ultrafast Optics on-line via Nanohub.org.

目的 目的是研究用于生成光学频率梳的新型电光和非线性光学方法，并探索此类新型光源的新应用。 智力优点将光学频率梳（一种彻底改变了频率计量学的技术）与脉冲整形技术相结合，提供了新的技术精确合成用户指定的相干超短脉冲场的能力，称为光学任意波形生成（OAWG）。 然而，OAWG 技术和应用最适合光学频率梳，其重复率明显高于电流源方便提供的重复率。 因此，提出了一个新的研究计划，首先关注用于高重复率频率梳生成的新颖光子学方法，其次关注由此实现的潜在变革性新应用。 生成方法包括电光相位调制和非线性光纤的新颖组合，并应用于数十 GHz 速率的光梳；以及波导微谐振器中的非线性波混频，重点是在更高的重复率（数百 GHz）下精确生成波形。 还提出了基于受合成孔径雷达启发的方法的高分辨率、远距离光学成像的研究，该方法通过基于梳的技术来测量光纤上的宽带光学相位。更广泛的影响 该项目应在领先研究小组的氛围中为尖端技术领域的广泛学生培训提供丰富的机会。两名博士学生已包含在提案预算中。 通过与国家标准与技术研究所的研究人员合作的机会，研究生培训将得到丰富。 本科生也将参与这项研究。 在该项目过程中，Weiner 教授还打算利用他最近出版的教科书，通过 Nanohub.org 将他的超快光学研究生课程放在网上。
