Abstract
In the one-dimensional metal photonic crystal made by stacking metal plates, it has been theoretically predicted that an incident light is amplified and that higher harmonics are generated by the interaction between light and the lattice vibration when the metal plates are artificially vibrated harmonically. When the vibration frequency of the lattice is rather large, the incident light can be amplified by just shaking the whole photonic crystal. In the present study, the lattice vibration frequency dependence of the transmission probability of the light with the same frequency as that of the incident wave is investigated in the case of shaking a whole photonic crystal, and a series of many resonance peaks of amplification is found out. It is shown that by comparing with photonic bands of higher harmonics, the amplification of light originates in resonance between the incident light and higher harmonics and that the resonant peaks are located on the band or band end of higher harmonics.
