Spectral plasmon signatures in sum- and difference-frequency generation

Prof. Sergey Ponomarenko

Department of Electrical and Computer Engineering, Dalhousie University, Halifax, NS, B3J 2X4 Canada

报告时间:56日上午9:00~10:00

报告地点:金陵院123会议室

报告简介

After a brief introduction into Surface Plasmon Polaritons (SPP) and surface nonlinear interactions, I will present my group’s results on sum- and difference-frequency generation with polychromatic light near SPP resonances in a Kretschmann configuration. I will describe pronounced spectral shifts and giant spectral modifications in the sum- and difference-frequency fields at the SPP resonance. I will compare and contrast the sum and difference frequency cases. Finally, I will outline potential applications of our results to ultra-sensitive surface sensors.

个人简介

Sergey Ponomarenko earned his Ph.D. degree in theoretical optical physics from the University of Rochester, USA under the tutelage of Prof. Emil Wolf, a founder of classical optical coherence theory. Prior to joining Dalhousie University, Canada as a tenure-track faculty and a Canada Research Chair in 2006, Dr. Ponomarenko had held a Director’s Postdoctoral Fellowship at Los Alamos National Laboratory, USA from 2004 to 2006. In 2010, Dr. Ponomarenko was promoted to Associate Professorship and his Canada Research Chair award was renewed. In his spare time, Dr. Ponomarenko tries to understand better fundamental aspects of optical coherence theory, nonlinear statistical optics and plasmonics with his graduate students and postdocs. He also enjoys track and half-marathon running, weight training, and an occasional badminton game among other sports activities.



部分相干激光束关联结构调控及应用基础

蔡阳健教授(苏州大学物理科学与技术学院)

报告时间:56日上午10:00~11:00

报告地点:金陵院123会议室

报告内容

部分相干激光束在许多领域具有独特的优势。传统部分相干激光束的空间关联结构满足高斯函数分布,近年来具有非传统关联结构的部分相干激光束受到越来越多学者的关注。具有特殊空间关联结构的部分相干激光束表现出自聚焦、自偏移、自分裂、自整形等奇特特性,在大气激光光通信、光学成像、微粒俘获和操控等领域具有重要的应前景。空间关联结构的调控为光束性质调控提供了一个崭新的手段。本报告将介绍部分相干激光束空间关联结构调控及应用基础方面的研究进展。
