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

Abstract

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<ω<ωp0; whereas well above ωp0, the effects of the time-variation are small. The parameter dependence of the effects is also calculated and discussed.
