Abstract
The dispersion compensation ability of a one-dimensional photonic crystal composed of dielectric and magnetized cold plasma materials has been theoretically investigated, based on the simple transfer matrix method in the near infrared region. Group delay, group velocity dispersion and third-order dispersion of the considered multilayer structure are deduced, and the propagating pulse shape correction in terms of external magnetic field is investigated for TE mode at normal incidence. The numerical simulations show that, for initially chirped ultra-short pulses, the external magnetic field controls both the pulse width and ripple. It is found that with the increasing of static magnetic field applied on the plasma layers, the pulse propagating through the structure reaches its minimum duration at shorter lengths of the crystal. The results of this study may be utilized to develop dispersion engineered ultra-short pulse laser systems. Moreover, the outcomes may also be useful in designing compact size tunable pulse compressors and pulse shapers.
