Abstract

Ultra-high speed optical transmissions require the knowledge of pulse broadening due to higher order dispersion. In this paper, we report the pulse broadening created by Lorentzian input pulse and it is compared with the pulse broadening created by Gaussian input pulse. The pulse broadening due to higher order dispersion terms are obtained for both Lorentzian and Gaussian input pulses. The output optical pulses created by Lorentzian input pulse are compared with the results obtained from Gaussian input pulse. This is followed by the estimation of intersymbol interference (ISI) and the maximum transmission length for Lorentzian input pulse is obtained. It is shown that intersymbol interference strongly depends on pulse profile. Further, the maximum transmission lengths are obtained for both Lorentzian and Guassian input pulses.
