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.
