The proposed integrated research and education program focusses oninvestigation of the notorious polarization instability and sensitivityto optical feedback of single transverse mode vertical cavity surfaceemitting lasers (VCSELs). These intertwined difficulties plague ongoingefforts to develop the use of single mode VCSELs for applications suchas wavelength division multiplexed communications networks and opticaldisk readout. Furthermore, we expect that our work will be relevant tofuture investigations of other low-dimensional semiconductor nano-laserswith a large degree of symmetry. The experimental investigations ofpolarization stability will be analyzed using a novel model that we havedeveloped to describe VCSELs with two polarization eigenstates in thepresence of optical feedback. This CW work will then be extended to aninvestigation of the small-signal modulation response of VCSELs withoptical feedback. Finally, the results of these investigations will beused to explore practical strategies for improving the stability andpolarization control of single mode VCSELs exposed to optical feedback.The proposed research will be integrated into the education of ourundergraduate physics and engineering majors, both in the classroom andvia direct participation of undergraduates in my research program. Inorder to enable our students to acquire the necessary research skills,we are developing a new investigative, inquiry-driven, sophomore-levelinstructional optoelectronics lab. In addition, we are introducing intoour introductory sequence pedagogical reforms aimed at encouragingstudents to engage in the processes of critical analysis that areessential to successful, creative research. Ultimately, thisintegration of research and teaching will contribute to the resolutionof a critical problem in VCSEL development while preparing ourundergraduates to join the ranks of the next generation of womenscientists and engineers.

该计划的重点是研究单横模垂直腔面发射激光器（VCSEL）的偏振不稳定性和对光反馈的敏感性。 这些交织在一起的困难困扰着正在进行的努力，以开发使用单模VCSEL的应用，如波分复用通信网络和光盘读出。 此外，我们希望我们的工作将相关的未来研究的其他低维半导体纳米激光器具有很大程度的对称性。 偏振稳定性的实验研究将使用一个新的模型进行分析，我们已经发展到描述VCSEL的两个偏振本征态存在的光反馈。 这种连续波工作将扩展到具有光反馈的VCSEL的小信号调制响应的研究。 最后，这些研究的结果将被用来探索改善暴露于光反馈的单模VCSEL的稳定性和偏振控制的实用策略。所提出的研究将被整合到我们的本科物理和工程专业的教育中，无论是在课堂上还是通过本科生直接参与我的研究计划。 为了使我们的学生获得必要的研究技能，我们正在开发一个新的调查，探究驱动，教学级光电子实验室。 此外，我们正在引入我们的介绍序列教学改革，旨在培养学生从事批判性分析的过程中，成功的，创造性的研究是必不可少的。 最终，这种研究和教学的整合将有助于解决VCSEL发展中的一个关键问题，同时为我们的本科生加入下一代女性科学家和工程师的行列做好准备。
