Although a monochromatic plane wave of a certain circular polarization state and wavelength may be almost completely reflected by a chiral sculptured thin film, we show here that information coded in rectangular pulses can still be transmitted across the film—provided the rise and fall times of the pulses are sufficiently small and the pulse widths are sufficiently large. © 2001 John Wiley & Sons, Inc.
