Confining Light in the Nanometer ScaleMichal Lipson, Cornell University0601460Intellectual Merit:The demonstration of novel efficient light emitters that consume very little power and are small in size on a chip-scale has been a goal of the scientific community. Such devices require the use of photonic structures, such as photonic crystals, which confine light in small dimensions and enhance light emission in specific directions through redistribution of the photonic density of states. Such structures are usually limited in size to the order of the wavelength of light, which in turn induces a limited enhancement of the light emission efficiency, proportional to the degree of confinement. Here it is proposed to remove this limitation on the degree of light confinement by demonstrating extremely low optical modal volumes experimentally. The ability to increase the confinement of light well beyond the levels achieved with traditional photonic structures has the potential for increased light emission as well as modulation. Broader Impacts:The fundamental knowledge gained by studying strong light confining structures for increased light emission has direct importance for a wide variety of novel applications such as amplification, sensing, lasing and switching that can be massively integrated on a chip-scale. As part of the educational effort it is proposed to develop an educational program for exposing students to photonics as an interdisciplinary area and enhancing the undergraduate and graduate Electrical and Computer Engineering curriculum in the area of photonics. An interdisciplinary seminar series will be developed for undergraduate and graduate students, and novel subjects of photonics will be introduced through lectures and laboratories in two courses in the ECE department at Cornell University.

在纳米级鳞片中限制光线，康奈尔大学0601460Intlectual的优点：新型有效的光发射器的演示，消耗的功率很少，并且在芯片规模上的大小很小，这是科学界的目标。这样的设备需要使用光子结构，例如光子晶体，这些光子晶体将光限制在小尺寸的光线，并通过对状态的光子密度的重新分布来增强特定方向的光发射。这种结构的大小通常限制在光的波长的范围内，这反过来又导致光发射效率的有限提高，与限制程度成正比。在这里，建议通过实验证明光学模态量极低，以消除对光限制程度的限制。将光线限制在传统光子结构中达到的水平之外的限制的能力具有增加光发射和调制的潜力。更广泛的影响：通过研究强烈的光限制结构来增加光发射的基本知识对各种新型应用，例如扩增，传感，激光和切换，可以大规模整合在芯片规模上。作为教育努力的一部分，建议制定一项教育计划，以将学生视为跨学科领域，并增强光子学领域的本科和研究生电气和计算机工程课程。将为本科生和研究生开发一个跨学科研讨会系列，光子学的新颖主题将通过康奈尔大学ECE系的两个课程的讲座和实验室引入。
