Transmission characteristic of terahertz wave band in 2D honey-comb lattice 2D photonic crystal

运用平面波展开法优化了太赫兹波段蜂巢晶格二维光子晶体带隙结构,数值模拟得到了太赫兹波段蜂巢晶格光子晶体的最大TE模、TM模和完全带隙,通过光子晶体态密度分布进一步验证了所优化的带隙结构,并设计了对应带隙范围的太赫兹波器件。研究结果为太赫兹器件的开发提供了理论依据。

Band gap of terahertz wave in two - dimensional honey - comb lattice photonic crystal are optimization design with the plane - wave expansion method. The honey - comb crystal lattice of TE mold , TM mold and complete band gap in two - dimensional photonie crystal are calculated. The photonie density of states is calculated to verify the performances of these tembertz photonic crystal characteristics. And devices of terahertz wave has designed. This research provides a theoretic basics for the development of terahertz wave devices.
