Figure 5

Intraband-interband contribution analysis of HHG in the SBE simulations. (a) High-harmonic spectra simulated for the intraband current (red area), interband polarization (blue area), and total contribution (dashed curve). (b–d) Polarization analysis of the simulated high-harmonic signals.
