等离子体光子晶体是等离子体学科和光子晶体学科交叉的产物,它不仅具有一般光子晶体的性质, 而且还体现等离子体的特性,通过改变等离子体参数或外加磁场可有效控制其带隙。若在可调带隙的等 离子体光子晶体中构造适当缺陷,则可形成可调滤波器和波导等器件,在工程方面具有重要应用。 结合本课题组工作,综述了等离子体光子晶体的研究进展,在此基础上,展望了等离子体光子晶体的发 展前景,为人们进一步研究等离子体光子晶体的特性和应用提供参考。

Plasma photonic crystal is a combinative production of plasma subject and photonic crystal subject. It not only shows photonic band gaps and local characteristics of conventional photonic crystals, but also has physical characteristics of plasma. The unique property of plasma photonic crystal is the tunable band gaps by plasma parameters as well as external magnetic field. If appropriate defects are introduced in plasma photonic crystals, tunable filters and waveguides can be formed and have important application in engineering. Combined with the research of our group, the process and prospect of one-dimensional and two-dimensional plasma photonic crystals are summarized, respectively, which would provide guidance for further studying on plasma photonic crystals.
