基于左手材料波导的慢光产生

通常右手材料中实现慢光的方法包括改变材料色散和波导结构色散,而左手材料的提出除了可以利用上述方法外还为慢光技术的实现提供了全新的方法,并具有室温固体条件下易实现的优点。分析了利用左手材料实现慢光的两种机理,并介绍了当前利用含有左手材料的波导结构实现慢光的研究进展和成果,最后对左手材料在慢光领域的应用做了总结。

Slow light based on negative refractive-index material

Two ways can be used to generate slow light in ordinary right-hand materials through changing the material dispersion and the structural dispersion.With left-handed materials,instead of the above two approaches,slow light can be realized through the cancellation of power flows at the interface of right- and left- handed materials.In this paper,the recent research progresses in the realization of slow light in left-handed materials with negative refractive-index are reviewed.
