Abstract

We computed three measures each of the durations and average speeds of ultrashort optical pulsed plane waves transmitted through linear and nonlinear chiral sculptured thin films (STFs). The durations tended in general to decrease with increasing carrier wavelength (save for an exception involving the circular Bragg phenomenon), while average speeds tended to increase under the same conditions. Durations tended to increase with increasing nonlinearity displayed by the chiral STF, while average speeds tended to decrease. The results quantify some aspects of ultrashort optical pulse shaping by chiral STFs, which heretofore had only been studied qualitatively.
