中文摘要： 时间隐身是光物理研究中一项令人惊奇的新概念和新技术，在通信安全等方面有着重要的应用前景。时间隐身的关键核心在于光信号传输时间速度的精确操控与配合，而光纤快慢光技术在此方面有着得天独厚的优势，时间隐身将为光纤通信系统带来崭新的应用平台。项目拟利用我们基于光纤受激布里渊散射的快慢光的系列性成果，提出准确调控光信号的传输速度与时间，并实现大时间间隙的全光控制。并利用布里渊振荡腔技术实现低损耗快光，避免快光信号强烈衰减对时间空隙的限制。重点突破纳秒量级以上的时间间隙的新途径和技术关键，这一量级的时间间隙可以容许加入调制器等光器件进行各种信号的隐身操作，并系统研究真实信号的隐身和反隐身技术的新途径及其物理限制因素。相信日臻成熟的光纤快慢光技术必将为时间隐身这一新颖思想带来全新的技术手段和新的应用。

英文摘要： Recently conception of time cloak (TL) opened a new surprising and interesting technology in the study of optics physics. It has a very important application prospect in strengthen security of communication and is widely concerned. The key in time cloak technology is the time and speed control of light signal transmission with precision, in which fast and slow light in the optical fiber has unique advantages and good performce. This project will propose a new time closk scheme with an accurate control of the light signal speed based on stimulated Brillouin scattering in optical fibers and realize all optical control of the time gap.Lossless fast light will be demonstrated experimentally by using Brillouin lasing oscillation cavity to avoid the limit of time gap. The key technology of time gap with nanosecond magnitude will be our research focus in order to realize all kinds of signalcloak operation with devices such as modulator.Also, this project will study new approaches and physical limiting factors of the time cloak and anicloak technology. Advanced fast/slow technique in optical fiber will bring new method and technology for time cloak.
