中文摘要: 负折射材料具有一系列违反常理的物理效应存在。申请者读博期间已用硅材料设计了对于10.6微米激光等效折射率为负数的二维光子晶体棱镜,在国际上首次观测到了光频段的反常多普勒现象,证明了人造负折射材料确实具有这种奇异的物理性质,相应论文已于2011年4月发表在Nature Photonics(Vol.5,No.4)杂志上。在此相关研究的基础上,拟进一步研究负折射光子晶体的反常古斯-汉欣位移效应。通过理论设计并制备相应的光子晶体结构,然后理论上设计相应的反常古斯-汉欣效应实验方案并进行实验探索。通过分析、研究实验数据,结合数值模拟仿真以及现有的理论研究成果,探讨负折射光子晶体中发生反常物理效应的内在物理机制,以期为负折射光子晶体的设计及其潜在应用领域的研究工作提供理论基础。

英文摘要: Material of negative refraction has a series of counterintuitive physical effect. By utilizing Silicon material, the applicant designed two-dimensional photonic crystal prism which has negative refraction for 10.6 micron laser. We first observed the inversed Doppler effect in optical frequency, proving that the artifical negative refractive material has this strange physical properties during the period of the Doctor pursuing.The corresponding papers have been published in NATURE PHOTONICS in 2011,5(4). Based on the relevant research results, we expect to further study the anomalous Goos-Hanchen shift effect in photonic crystal of negative refraction.Through theoretically designing and preparing corresponding photonic crystal structure, we further theoretically design and implement the experimental scheme. By analyzing and studying the experimental data and combining the numerical simulation with the existing theoretical research results, we try to probe into the internal physical mechanisms of the abnormal physical effects in photonic crystal of negative refraction and expect to provide theoretical basis for the design and potential applications of photonic crystal with negative refraction.
