中文摘要: 目前,对驻波场诱导的周期性量子干涉效应在存储光信息和产生静止光方面的研究已经很深入,但在可调谐光子带隙、控制光传输和光学器件开发上的研究还很有限,因此本项目拟开展这方面的研究。 具体内容包括:(1)在掺镨硅酸钇或NV色心钻石单晶钇等固体材料中建立电磁感应多光子带隙结构,从色散谱和反射谱角度研究耦合场参数对带隙的操控和优化,在此基础上分析带隙的退化和简并;(2)结合电磁感应光透明技术,研究光脉冲在双带隙结构中的传播特性,建立双通道全光路由并分析路由的传输效率及限制条件,然后进一步考虑如何建立多通道全光路由;(3)建立合适的能级模型,研究如何在第二布里渊区建立可调谐光子带隙,并探讨利用里德堡原子在更高布里渊区获得光子带隙的可能。

英文摘要: Nowadays, in-depth researches about periodically modulated quantum interference have been put up on light storage and generation of stationary light. However, the researches about that on photonic band gap (PBG), controlling of light propagation and developing optical devices are elementary, thus we plan to develop these researches in this project. Firstly, we study the establishment of multiple band gaps in solids such as presodimium-doped yttrium orthosilicate and diamond containing nitrogen vacancy (N-V) color centers, and according to the dispersion and reflectivity spectrum, research the tuning to the band gaps by the parameters of coupling fields. Then we analyze the degeneration of the band gaps. Secondly, associating with the electromagnetically induced transparency, we investigate the propagation of light pulses in a double-PBG structure in order to develop a two-channel routing. Then we analyze the efficiency and limitation of the routing, and consider the possibility of developing a multiple-channel routing. Thirdly, by choosing a reasonable energy-level model we study how to develop the PBG structure in the second Brilliouin zone and discuss the possibility of developing the PBG in a higher Brilliouin zone with Rydberg atoms.
