【摘要】 近年以来,光速减慢即慢光(vg<c,vg为光在介质中传播的群速度,c为真空中的光速)作为一种新的物理现象,以及其具有的潜在应用前景,在物理学、光学、材料学等领域越来越引起人们的重视。但是,从一定程度上来说,关于慢光的研究作为一个很新的课题目前还有很多方面不完善,对于很多基本的物理机制和实践问题还有待解决。作者正是从目前该领域现状出发,研究了基于耦合谐振透明效应技术的慢光的理论和实验,目的是进一步对慢光的本质加以研究,并为慢光的应用提供理论和实验的支持。首先,本文介绍,并回顾了最近几年慢光和超光速领域的相关研究进展,重点介绍了包括电磁感应透明技术和耦合谐振透明技术等实现慢光的技术。第二,介绍了光速减慢的理论基础:光在介质中的几种速度,以及群速度理论的发展。第三,发展了耦合谐振透明的理论,研究了基于耦合谐振透明实现的慢光的原理和性质,并且就耦合谐振结构的各个参数对慢光性质的影响做了研究。第四,在光纤中实现了耦合谐振透明的效应,并运用两种实验方法观察到了光速减慢的现象。并且将其中一种方法观察到得实验结果与理论进行了对比,实验结果和理论符合得较好。本论文的研究成果发展了基于耦合谐振透明技术的慢光的理论和实验方法。对于更进一步的研究提供了理论和实验指导,并为慢光技术的发展和应用提供了相应的支持。更多还原

【Abstract】 In recent years, slow light(vg<c,vg is the group velocity of light in media, c is the speed of light in vacuum), as new physical phenomena, have attracted great interests in researchers in optics and material for their potential application in telecommunication and optical signal processing. Undoubtedly, as a new issue, researches in slow light are still in progress and many fundamental problems need to be solved, to some extent. Faced on the reality in this field, the author investigated the theoretical model and the experiment of the slow light based on coupled-resonator-induced transparency. Through detailed experimental observation, we find that our experimental results confirm the theoretical prospect. Our results on slow light in Coupled-resonator-induced transparency will be helpful on the understanding of the related phenomenon and will be of significance on the future application of slow light.Firstly, the author reviewed the recent progress on the research of slow light. Also, the technologies including electromagnetically induced transparency, coupled-resonator-induced transparency based on which slow light is obtained are reviewed.Secondly, the different definitions of the light speed are introduced, and the progress in the theory of the wave packet propagation is demonstrated.Thirdly, the theoretical mode of coupled-resonator-induced transparency has been improved in optical fiber field, and the author demonstrated the principle and the property of the slow light based on coupled-resonator-induced transparency.At last, the author performed the effect of coupled-resonator-induced trans-parency(CRIT) in optical fiber, and the slow light based on the CRIT is observed in two ways. In one way, the experimental measured data fit the theoretical results well.Our researches enrich the theoretical and experimental investigations on slow light based on the coupled-resonator-induced transparency. These results will be of significance on the investigation in related fields in the future and will back up the possible application of slow light.更多还原
