摘要:

自由电子束通过周期性分层金属/电介质结构中的纳米孔的通道产生了一种新型的可调谐的纳米级辐射源-"光阱"。这种光阱的横向尺寸仅为几百纳米,发射强度约为200 W/cm ^2,可用于纳米光子电路中作为芯片级光源,或用于光学存储器和显示器应用中的密集封装集成。

英文摘要:

The passage of a free-electron beam through a nano-hole in a periodically layered metal/dielectric structure creates a new type of tuneable, nanoscale radiation source - a 'light-well'. With a lateral size of just a few hundred nanometers, and an emission intensity of ~200 W/cm^2 such light-wells may be employed in nanophotonic circuits as chip-scale sources, or in densely packed ensembles for optical memory and display applications.
