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。
The concept of photonic crystals has been proposed for more than two decades now. Due to its unique band gap and defect structure, it can be used to control the propagation of photons. Compared with the traditional semiconductor crystal-based electronic technology, photonic crystals are more promising in the future. Photonic crystals and photons The core of communication technology research and development. In recent years, based on new materials, new methods have been produced with a complex structure of photonic crystals continue to emerge, its range of applications from the earlier waveguide, optical switches, mirrors extended to sensors, super prisms, microlenses, solar cells, enhanced LED Luminescence, optical storage, bio-chip, bionic and other emerging fields. This article combines the latest research status, discusses the photonic crystal preparation and application progress.
