光子晶体器件的研究进展及前景

Progress and future of photonic crystal devices

光子晶体器件是近年来迅速发展起来的一类微纳器件,可以操控光子的运动行为,并具有损耗极低、体积小、易集成的优点。本文综合论述了光子晶体器件的几种主要设计方法的优缺点、指出了加工制作中的技术难点所在,还介绍了两种常用的耦合技术,最后对光子晶体的未来作了展望。

The photnic crystal devices(PhCD)can manipulate the behavior of photons with the advantages such as lower energy loss,smaller size and more easy to integrate on a chip. In this paper some capital design methods and theories of PhCDs were summarized,then the technological difficult points in the fabrication were pointed out and two important coupling technologies were introduced. We also give a perspective about the PhCDs in the end.
