The reflection and transmission of optical videopulses incident axially upon a slab of a chiral sculptured thin film (STF) is studied using a finite-difference simulation in the time domain. Videopulse bleeding is shown to occur when the handedness of the carrier plane wave matches the structural handedness of the chiral STF and the carrier wavelength lies in the Bragg regime.
