0226872BrioThis award supports the PI and graduate students from the University of Arizona in a collaboration with Mads Sorenson of the Department of Informatics and Mathematical Modeling at the Technical University of Denmark in Lyngby. The research will focus on two physical problems. One is the study of integrated photonic devices; a second is the propagation of ultra short pulses and beams in nonlinear media, including air. The problem of femtosecond light pulses in bulk media is a challenging computational problem because the high intensity of the laser pulse can cause optical breakdown of the material leading to highly nonlinear response. Recently developed efficient parallel algorithms will be applied to the problem of modeling ultra short pulses in nonlinear media. For the study of short pulse dynamics in photonic crystal fibers, theoretical calculations will be done to investigate supercontinuuum generation, soliton self-frequency shift, and third-harmonic generation.The combined effort of the US and Danish groups is expected to provide a much needed theoretical and numerical component to the important technologies associated with applications of ultra short pulse phenomena. The topic area has the potential to produce revolutionary advances in the fields of communications, medicine, energy efficiency, defense, and manufacturing.

该奖项与林格比丹麦技术大学信息学和数学建模系的Mads Sorenson合作，为亚利桑那大学的PI和研究生提供支持。研究将集中在两个物理问题上。一个是对集成光子器件的研究；另一个是超短脉冲和光束在包括空气在内的非线性介质中的传播。块状介质中的飞秒光脉冲问题是一个具有挑战性的计算问题，因为高强度的激光脉冲会导致材料的光学击穿，从而导致高度的非线性响应。最近发展起来的高效并行算法将被应用于非线性介质中超短脉冲的建模问题。在研究光子晶体光纤中的短脉冲动力学时，将对超连续谱产生、孤子自频移和三次谐波产生进行理论计算。美国和丹麦小组的共同努力有望为与超短脉冲现象应用相关的重要技术提供急需的理论和数值组件。该主题领域有可能在通信、医学、能源效率、国防和制造领域产生革命性进展。
