中文摘要：

光子晶体概念的提出到现在已有20多年,由于其特有的带隙和缺陷结构可实现对光子传播的控制,与传统的基于半导体晶体的电子技术相比更具优势,是未来光子计算机和光子通讯技术研发的核心。近年来,基于新材料、新方法制备的具有复杂结构的光子晶体不断涌现,其应用范围也从较早的波导、光开关、反射镜拓展到传感器、超棱镜、微透镜、太阳能电池、增强LED发光、光存储、生物芯片、仿生等新兴领域。本文结合了最新的研究状况,探讨了光子晶体的制备与应用进展。

英文摘要：

The concept of photonic crystals has been born for over 20 years.Having the photonic band gaps in structure,photonic crystals have novel properties and potential applications in many areas.The movement of photons is controlled so well in photonic crystals that they are considered as the core materials to realize photonic computers and communications in the future.Compared with the electron technology,the photonic crystal based photon technology has more advantages especially in efficiency,bandwidth and energy saving.Some new preparation methods and application of the photonic crystals were summarized in this paper.
