摘要
应用多光子非线性康普顿(Compton)散射模型和时域有限差分方法,研究了多光子非线性Compton散射对可调缺陷层等离子体光子晶体滤波的影响。结果表明,等离子体缺陷层几何厚度不变时,随缺陷等离子体层电子密度的增大,多光子非线性Compton散射使缺陷模透射峰频率向高频方向迅速移动,缺陷模中心频率向高频方向近乎线性地迅速移动。等离子体缺陷层厚度增大时,多光子非线性Compton散射使缺陷模的中心频率向低频方向移动;厚度增加到一定值时,在带隙上边沿处产生一个高于Compton散射前频率的缺陷模频率。
Using the multi-photon nonlinear Compton scattering model and finite-difference time-domain（FDTD） algorithm,the influence of the filter wave of the plasma photonic crystals with tunable defect by the multi-photon nonlinear Compton scattering is studied.The results show that when the geometrical thickness of the plasma tunable defect is a constant,the transmission spectra frequencies of the defect mode are quickly moved to the high frequency direction along with the increases of the electric density in the plasma tunable defect by the multi-photon nonlinear Compton scattering,and its central frequencies nearly are linearly and quickly moved to the high frequency direction.When the geometrical thicknesses of the plasma tunable defect are increased,the central frequencies of the tunable defect mode are moved to the low frequency direction by the multi-photon nonlinear Compton scattering.The thickness is increased to the certain numbers,a higher tunable defect mode frequency than before Compton scattering is taken place on the upper part of the border of the band gap.
