非线性光学研究新进展

非线性光学的研究包括从物质与激发的相互作用的基本原理到用于光通信、医疗及生物技术的设备、元件和系统的研究。近些年来,围绕非线性光学的基础理论与应用研究主要集中源技术、光通信技术及材料的非线性调控等几个方面。在激光光源方面,强场和阿秒非线性光学得到了广泛的研究,白光激光光源也得到了人们的关注;在光通信领域,通过微纳结构光波导的设计来调控其色散特性,达到信号无损传输或光路集成的应用目的;而光学非线性研究离不开材料,因此,微腔和表面等离子体调控光学非线性成为人们研究的热点。

New Progress in Nonlinear Optics Research

Nonlinear-optics activities range from the fundamental studies of the interaction between matter and radiation to the development of devices,components,and systems of tremendous commercial interest for widespread applications in optical telecommunications,medicine,and biotechnology.During recent years,research efforts in nonlinear optics focused on source technology,light communication technology and engineering or enhancing nonlinearities.As an aspect of laser source,high field nonlinearities and Attosecond technology obtained huge progress widely.Importantly,more and more groups are employing new white-light-laser sources for their experiments.In the area of light communications,nonlinear propagation of light and engineerable group-velocity dispersion(GVD) in engineered waveguides become focus.Moreover,nonlinear material is the basic of nonlinear science.It is a new hot spot to manipulate nonlinear response and enhance nonlinearities by Microcavity and surface plasmonic.
