Ultrafast optical field incident on material with broken spatial symmetry (blue), time-reversal symmetry (yellow), or both (green) to generate THz radiation. Insets illustrate various mechanisms that lead to rectified THz currents high-frequency optical fields. (Image courtesy of Los Alamos National Laboratory)
