The confusion apparently stems from the fact that our paper [Appl. Opt. 44, 5937 (2005)] dealt with modulated pulses, modulated at terahertz frequency, while Mendis' paper [Appl. Opt.47, 4231 (2008)] dealt with narrow-baseband pulses that may contain a very large (terahertz) spectral width. Therefore, the criticism given by Mendis is erroneous, since his analysis is for baseband pulses only.
