Photonic band structures of 1-D plasma photonic crystal with time-variation plasma density

The photonic band structures of one-dimensional plasma photonic crystal (1-D PPC) with time-variation plasma density are studied by using differential transfer matrix method. Taking an exponential functional form of time as an illustration of the time-varying plasma density, we examine the photonic band structures of the 1-D PPC. The results show that the photonic band structures can be tuned correspondingly by changing the time which modifies the plasma dielectric constant in different frequency regions, especially in the range of 0 < omega < omega(p0); whereas well above omega(p0), the effects of the time-variation are small. The parameter dependence of the effects is also calculated and discussed. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4707403]
