Figure 2. Simulation results of other input pulse shapes.

(a), (b) and (c) the deviations between the output waveform and the OD (blue circle) and the OHT (red square) as a function of the defined filter's 3-dB bandwidth with input of Sech² pulse, super-Gaussian pulse and Hermite-Gaussian pulse, respectively; insets (a1–c1) show the corresponding output waveforms (red solid line) of the defined filter, ideal OD waveform (green dot line) and ideal OHT waveform (blue dash line) with certain 3-dB bandwidths of the defined filter.
