Abstract

Recent advances in understanding of ultrashort pulse propagation in multilayered AZO/ZnO ENZ metamaterial are presented. The influence of the material parameters for AZO/ZnO metamaterial on chromatic dispersion are discussed. Numerical approach based on a full wave analysis of the ultrashort pulse propagation in the presence of enormous second-order dispersion was used to investigate ultrashort pulse propagation through ENZ AZO/ZnO metamaterial. An approach using an adaptive pre-shaping algorithm for ultrashort pulse distortion compensation during the propagation at the ENZ spectral point is introduced. The results based on auxiliary differential equation finite-difference time domain method that show a dramatic change in shape for the probe pulse modulated using pump pulses of various duration (100-500 fs) and amplitude (106−1010 V/m) are presented.
