International Research Fellowship Program: Organic Microlasers for Photonics

0202631赖特国际研究奖学金计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。 该计划的奖项提供了联合研究的机会，并使用独特或互补的设施，专业知识和国外的实验条件。该奖项将支持由丹尼尔赖特博士与约瑟夫Zermina博士在法国卡雄的L'Ecole Normale Cachan de卡尚进行为期12个月的研究奖学金。 该项目将得到数学和物理科学理事会多学科活动办公室的共同支持。该项目将推动卡尚高等师范学校约瑟夫·扎雷博士实验室对有机微激光器的研究。 本文的研究主要集中在两个方面，一是激光增益介质，二是激光反馈结构。 关于增益介质的工作将集中于开发在光谱的近红外部分中在1.3和1.55 μ m的工业上有用的波长下工作的有机微激光器，因为目前没有在这些波长下工作的有机激光源。 该项目将需要检查掺杂稀土离子的新聚合物，这些聚合物可以在该光谱区域提供有效的激光。 PI在微激光腔设计方面的工作将集中在通过制造具有工程缺陷的有机微盘结构来改善这些器件发射的方向性，并探索其他平面腔形状，如椭圆形，多极和多边形。 他随后将研究这些平面腔与光纤、波导和其他微盘的耦合。 为了表征和改进反馈结构，他将进行实验，其中每个新腔的发射光将被收集，以便可以检查光的角度依赖性和光谱特性。 这些实验的结果将与所研究系统的数学模型进行比较。Zelvis博士是有机非线性光学和光子学的主要研究人员之一。

0202631WrightThe International Research Fellowship Program enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will support a twelve month research fellowship by Dr. Daniel Wright to work with Dr. Joseph Zyss at the L'Ecole Normale Superieure de Cachan in Cachon, France. This project will be co-supported by the Math and Physical Sciences Directorate's Office of Multidisciplinary Activities.This project will advance research on organic microlasers in the lab of Dr. Joseph Zyss at the L'Ecole Normale Superieure de Cachan. The research will be directed in two areas, one focusing on the laser gain media and the other on the laser feedback structure. The work on the gain media will concentrate on the development of organic microlasers that operate in the near infrared portion of the spectrum at the industrially useful wavelengths of 1.3 and 1.55 um since there are currently no organic laser sources that work at these wavelengths. The project will entail the examination of new polymers doped with rare-earth ions that could provide efficient laser light in this spectra region. The PI's work on microlaser cavity design will focus on improving the directionality of the emissions of these devices by fabricating organic microdisk structures with engineered defects and also exploring other planar cavity shapes such as ovals, mulipoles, and polygons. He will subsequently investigate the coupling of these planar cavities to optical fibers, waveguides, and other microdisks. In order to characterize and improve the feedback structures, he will perform experiments in which the emitted light of each new cavity will be collected such that the angular dependence and spectral properties of the light can be examined. The results of these experiments will be compared to mathematical models of the systems under study.Dr. Zyss is one of the leading researchers in organic non-linear optics and photonics.
