摘要
光子晶体是一种具有光子带隙的周期性电介质结构,落在光子带隙中的光不能传播。由于其独特的调节光子传播状态的功能,成为实现光通讯和光子计算机的基础。光子晶体的制备是发展光子晶体的关键,而可见光和近红外波段光子晶体的制备更是难点。本文阐述了光子晶体的概念及其特性后,分别介绍了光子晶体的实验研究和应用研究。实验研究重点介绍了光子晶体的制备方法。应用研究重点介绍了单模发光二极管光、光波导器件和微波天线等。
Photonic crystals are materials with regular periodicity of dielectric structures, which can create a range of forbidden frequencies called photonic bandgap. Photons with energies lying in the bandgap cannot propagate through the medium. Moreover, photonic crystals have the ability to manipulate, confine and control light, thus provide the opportunities to shape and mould the flow of light for photonic communication technology and photonic computer. In present,the preparation of photonic crystals,especially those in visible or near-infrared region,is the key to the development of photonic crystals. In this paper, the conception and characteristics of photonie crystal are described at first, and then the research in experiment and application are introduced respectively. In experiment research, fabrication method of photonic crystals is depicted. In application, single-mode light-emitting diode, optical waveguide device and microwave antenna are described.
