General audience abstract:The beam of light coming from a laser is typically brightest in the middle becoming dimmer towards the edges and keeps that basic pattern as it moves through space. It is possible to manipulate such a beam to produce one with much more complicated patterns across and along the beam. The PI and his students will be continuing the exploration of such novel light beams and their applications. Such studies may have an impact in the creation of new types of imaging for medical diagnosis and new ways for increasing the amount of information carried by light in communications. The PI and his team will investigate one type of novel light beam, known as a non-diffracting beam which has the interesting property of not spreading or shrinking, at least over a limited distance. Such beams can be used to simulate physical situations that may be intractable to investigate by other means, or give complementary perspectives to present-day studies. This type of research will offer new approaches for the creation of novel light-based technologies. In this research the PI and co-workers, mostly undergraduates, will use emerging technologies in light manipulation to reshape and study light in new ways. Immediate byproducts beyond the main research include creating new instructional laboratories designed to educate an emerging workforce that must understand the quantum physics used in new technologies.Technical audience abstract:In this study the PI and coworkers aim at manipulating light beams to study scalar and vectorial light patterns in new spatial arrangements of amplitude, phase and polarization, which evolve and redistribute as the light propagates. These patterns are known as non-diffracting beams. The group will study optical singularities in these beams, such as optical vortices and caustics, in arrangements that have not been previously investigated. These new configurations of fields are important because they unravel underlying phenomena that are not easily predicted. A particular problem that will be investigated uses light to simulate quantum mechanical problems due to similarities between the Helmholtz wave equation and the Schrodinger equation. The researchers will also study new polarization patterns in three dimensions that involve rotations of the polarization ellipse that mimic twisted patterns of spins. They will do these investigations classically as well as quantum mechanically via experiments with single photons. At the quantum level, the studies will involve new spatial correlations that involve the propagation dimension. These studies open new paradigms for understanding light-wave patterns and to use them in photonic applications such as imaging, manipulation and communications.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

普通观众摘要：来自激光器的光束通常是中间最亮的光，在边缘变暗，并在其穿过太空时保持基本模式。 可以操纵这种光束，以产生横梁和沿梁的复杂图案更为复杂的光束。 PI和他的学生将继续探索这种新型光束及其应用。这样的研究可能会影响用于医学诊断的新成像的新型成像，以及增加通信中光携带的信息量的新方法。 PI和他的团队将研究一种新型光束，被称为非裂开光束，其具有不扩散或收缩的有趣属性，至少在有限的距离内。 这样的光束可用于模拟可能需要通过其他方式研究或给出当今研究的互补观点的身体情况。这种类型的研究将为创建新型的基于光的技术提供新的方法。在这项研究中，PI和同事（主要是本科生）将在轻度操纵中使用新兴技术以新的方式重塑和研究光线。主要研究以外的直接副产品包括创建新的教学实验室，旨在教育新的劳动力，必须了解新技术中使用的量子物理学。技术受众摘要：在这项研究中，PI和同事旨在操纵光束，以研究量表和矢量光模式在新的空间安排中，并将光度安排在光层和层次上，并置于阶段和层次化，并逐步化，并将其置于阶段和层面上。这些模式被称为非划分光束。该小组将研究这些光束中的光学奇异性，例如光学涡旋和苛性镜，在以前尚未研究的布置中。这些新的田地配置很重要，因为它们揭示了不容易预测的基本现象。由于Helmholtz波方程与Schrodinger方程之间的相似性，将使用光使用光的特定问题来模拟量子机械问题。研究人员还将在三个维度上研究新的极化模式，涉及模仿旋转扭曲模式的极化椭圆的旋转。他们将通过具有单个光子的实验机械地进行经典和量子进行这些研究。在量子水平上，研究将涉及涉及传播维度的新空间相关性。这些研究开辟了新的范式，以理解光波模式并将其用于影像，操纵和通信等光子应用中。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响来评估的评估值得支持的。
