The objective of this proposal is to explore, both experimentally and theoretically, new concepts related to the propagation of optical waves in periodic arrays of optical waveguides. Intellectual Merit: We are all aware of the historically extraordinary difference in behavior between a single atom and the collective behavior of a periodic array of atoms that are organized to form a solid. Interestingly, today we have a similar opportunity to study and perhaps to engineer the corresponding difference in optical behavior between a single waveguide and the extraordinary collective behavior of an array of waveguides. For example, our study of small deviations from periodicity of a waveguide array will allow us to better assess and take advantage of the role of defects in both linear and nonlinear periodic structures. In addition, we are always looking for way to control and to minimize diffraction effects, especially losses, and our investigation will further our understanding and perhaps more importantly, the management of diffraction in periodic waveguide arrays. Finally, our proposal also includes exploring the inclusion of quantum dots in waveguide array structures and therefore offers an exciting way to enhance their nonlinear behavior and open new applications. Broader Impact: All of the proposed research topics challenge basic fundamental questions with some having direct implications in other fields beyond optics. Moreover, we also propose an outreach effort that brings hands-on inquiry based lessons in optics to K-12 science education and attracts under-represented students into optical sciences and engineering. Finally, add to this picture our students designing waveguides, fabricating them, and analyzing them. This is an educational experience that spans the range from basic optical science to operating devices - a beautiful way to learn many old and new concepts in optical engineering.

该提案的目的是在实验和理论上探索与光波中光波的传播有关的新概念。知识分子的优点：我们都意识到一个原子与周期性原子的集体行为之间的历史上的非凡差异，这些原子构成了固体。有趣的是，今天我们有类似的研究机会，也许是为了设计单个波导与一系列波导的非凡集体行为之间的光学行为差异。例如，我们对波导阵列周期性的小偏差的研究将使我们能够更好地评估并利用缺陷在线性和非线性周期性结构中的作用。此外，我们一直在寻找控制和最小化衍射效应的方法，尤其是损失，我们的研究将进一步了解我们的理解，也许更重要的是，对周期性波导阵列中的衍射管理。最后，我们的建议还包括探索波导阵列结构中量子点的包含，因此提供了一种令人兴奋的方法来增强其非线性行为和开放新应用。更广泛的影响：所有拟议的研究主题都挑战了基本基本问题，其中一些人在光学范围之外的其他领域具有直接影响。此外，我们还提出了一项宣传工作，将基于动手询问的光学询问的课程带入K-12科学教育，并吸引了人数不足的学生进入光学科学和工程学。最后，添加到这张图片中，我们的学生设计了波导，制造它们并分析它们。这是一种跨越从基本光学科学到操作设备的教育体验 - 一种学习光学工程中许多新旧概念的美好方式。
